wasm-bindgen command provided is not valid

[rparrett]

In the "run" subsection of:

https://bevy-cheatbook.github.io/platforms/wasm.html#wasm-bindgen

Running the command

wasm-bindgen --out-dir ./out/ --target web ./target/

results in the error:

error: failed reading './target/'

wasm-bindgen is expecting the path to a wasm file, e.g. ./target/wasm32-unknown-unknown/release/myproject.wasm.

Maybe this was intended as more of a "command template," but the page doesn't offer any sort of instructions related to making the command actually work.
