Relates to #2750: Fix Substrate Docker

[ltfschoen]

The goal is to provide a fix so that if you run ./substrate/docker/build.sh from the project root directory of the polkadot-sdk, it will build a Docker container that has all relevant substrate-related binaries available.

That is the command that I've been running whilst using Docker Desktop for Mac 4.22.0 (117440), using macOS Sonoma 14.1.1.

I believe it should allow the user to have access to the binary of the following polkadot-sdk packages names:

• polkadot
• polkadot-parachain-bin
• staging-node-cli
• staging-chain-spec-builder
• subkey
• solochain-template-node
• parachain-template-node
• minimal-template-node
• test-parachain-adder-collator

where those packages generate the following binaries:

• polkadot
• polkadot-parachain
• substrate-node
• chain-spec-builder
• subkey
• solochain-template-node
• parachain-template-node
• minimal-template-node
• adder-collator

But NOT polkadot-parachain just yet, since it generates an error #4448.

So far I am trying to add support for all of those binaries, even though later some of those could go into a different Dockerfile, by specifically building those packages here.

So rather than building everything with cargo build --workspace --locked --release in the workspace, we allow them to choose specific packages that are relevant (or only those that don't generate an error).

The progress made in trying fix #2750 include this error:

Where the fix has just been to modify this line so it finds the Cargo.toml in the project root https://github.com/paritytech/polkadot-sdk/compare/master...ltfschoen:polkadot-sdk:fix-2750-substrate-docker-file?expand=1#diff-42b72709c8ec68097a5de02440c9263d5c0c3acbd13076b482183991597b8e49R6

The next error was:

150.5 error: failed to select a version for `env_logger`.

150.5  It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.

--------------------
ERROR: failed to solve: process "/bin/sh -c cargo build --locked --release" did not complete successfully: exit code: 101

Where the solution has been to go through each of the packages and change it like this https://github.com/paritytech/polkadot-sdk/compare/master...ltfschoen:polkadot-sdk:fix-2750-substrate-docker-file?expand=1#diff-19bdfdcfbc7d4526e1df401f04e4fa041ed5cc9ce9b44ec234dedf9301c7585cR46

Then the next issue was this error:

357.8 error: package `jsonrpsee-types v0.22.5` cannot be built because it requires rustc 1.74.1 or newer, while the currently active rustc version is 1.70.0

--------------------
ERROR: failed to solve: process "/bin/sh -c cargo build --locked --release" did not complete successfully: exit code: 101

That error is because at the top of substrate/docker/substrate_builder.Dockerfile here it depends on docker.io/paritytech/ci-linux:production that is using an old version RUST_NIGHTLY=2023-05-23 that breaks the build.

So to fix that I could either create a PR to modify https://github.com/paritytech/scripts/blob/master/dockerfiles/ci-linux/Dockerfile to use the latest Rust nightly version that is compatible with the latest polkadot-sdk, and if the PR gets merged then a new release of docker.io/paritytech/ci-linux:production would get created and that would hopefully resolve this issue.

But instead I decided to just add the proposed modifications here to resolve that error.

Then there was a warning

941.6 warning: /substrate/cumulus/client/relay-chain-rpc-interface/Cargo.toml: `default_features` is deprecated in favor of `default-features` and will not work in the 2024 edition
941.6 (in the `smoldot` dependency)

941.6 (in the `smoldot-light` dependency)

That I fixed here

Then there was another error that I resolved somehow (can't remember how I solved it)

Then I got error:

Which is because the node-template binary has been replaced with other templates in the ./templates folder of the polkadot-sdk that i mentioned earlier, such as solochain-template-node and minimal-template-node, so i've replaced that with the latest binaries here

Now that latest error that I've gotten has been the one that i've reported in this issue #4448, and i still haven't resolved it yet.

This PR now compiles.
