Debug GitHub Actions issue

I've been working on #1275, and haven't been able to get the added script in actions/zerocopy_toolchain_version/action.yml to produce output usable by workflows/ci.yml. In particular, ${{ steps.toolchain.outputs.toolchain }} always interpolates to an empty string.

I'd love it if someone with more GitHub Actions experience could take a look and see if they can figure out what's going wrong!

Edit: Happy to take over your branch as well and create a new PR.

It looks like adding the following here seems to do the trick:

outputs:
  toolchain:
    description: 'Resolved toolchain version'
    value: ${{ steps.resolve.outputs.toolchain }}

I followed the example from the doc.

Test run on my fork.

Note: I didn't see this as a GitHub issue, so wanted to flag the target clean up errors in this test run.

Target clean up errors

Originally, I thought I introduced these with the code change, but the errors appear in the official test runs as well. Example. It appears to be an issue with the action Swatinem/rust-cache, but haven't look into it further.

Amazing, thank you! I've also opened #1389 based on your observation about the target dir errors.
