Steps in "Build a sample app" do not work

[xJonathanLEI]

This is about:

• Innaccurate/misleading documentation (e.g. technically incorrect advice)

Problem

The Build a sample app page does not mention that the wasm32-unknown-unknown target must be added for the steps to work. In fact, such instruction in only given in a much later page in Project Setup.

New comers expect everything just works™ on a quickstart page. So I'd suggest adding this command to that page:

rustup target add wasm32-unknown-unknown

Questionaire

• I'd like to write this documentation

Still getting an error after following the steps...

Found issue with wasm bind-gen here
Had to do the following:
rustup target add wasm32-unknown-unknown --toolchain nightly
rustup run nightly trunk serve

Hi @xJonathanLEI,
I've been looking through the docs too and it seems like someone has beaten you to the punch as the requirement for target 'wasm32-unknown-unknown' was added by this PR #1907 🎉.

Now that PR #1907 is merged, I think this issue can be closed
