⚠️ Note that using getInput is NOT safe in a post action because if the calling workflow uses templated inputs, they will generally evaluate to something different in the post action:

- using: foo
  with:
    # Using 'x' in post is not safe
    x: ${{ some_templated_var }}

"Official workaround": https://github.com/actions/cache/blob/a7c34adf76222e77931dedbf4a45b2e4648ced19/src/restore.ts#L24-L25

Feel free to double check if this has changed in the past months

Note that NONE of the INPUTS.xyz will generally work as expected in the post action because they might be templated. You can try to just JSON-dump the entire INPUTS to the state.

Done.

Looks good!

Let's add a test (would've caught the bug below!)

Unrelated to this PR, I just saw that we have our own implementation of rmRf but we could also use io.rmRF.

Checking the state after the post action is not easy. You need to execute another action before p-w-m that executes your commands in their post action. Luckily, there is an action for that: webiny/action-post-run. Unfortunately, this action does not pipe the errors out and thus won't fail if an error occurs. This is fixed in the fork lisanna-dettwyler/action-post-run.
If webiny/action-post-run updates its action, we can use it. For now, let's stick with lisanna-dettwyler/action-post-run.

Whoops, early merge, let’s hope CI is good
