Publishing IPNS names

[LewisPringle]

in step 7 - unclear how you connect the ipns name to what it maps to with the publish command (only one cid specified).

Ack. The tutorial at:

https://docs.ipfs.tech/how-to/publish-ipns/#publishing-ipns-names-with-kubo

uses the implicit default key named self, which is the same publishing with ipfs name publish --key self

I agree, we should update this tutorial and generate a new key and then use it by passing --key.

@LewisPringle would you be interested in submitting a PR?
