default.run.working-directory property is not respected

[runlevel5]

What happened?

Please see example section

Example

I have a simple pipeline:

jobs:
  preview:
    name: preview
    runs-on: [self-hosted, small, arm64]
    defaults:
      run:
        working-directory: ./my-project # NOTE: my pulumi project resides in this folder
    steps:
      - uses: pulumi/actions@v5
        with:
          pulumi-version: ${{ steps.versions.outputs.pulumi }}
          command: preview
          stack-name: my-org/my-stack
        env:
          PULUMI_ACCESS_TOKEN: ${{ secrets.PULUMI_ACCESS_TOKEN }}

When running pipeline I got the error that could not find stack, simply because pulumi preview does NOT respect default.run.working-directory

In order to fix this issue I have to explicitly declare work-dir in pulumi/actions step:

      - uses: pulumi/actions@v5
        with:
          work-dir: ./my-project/

Output of pulumi about

It happens with all pulumi version from v4 to v5

The default.run documentation states the following:

Use jobs.<job_id>.defaults.run to provide default shell and working-directory to all run steps in the job.

Note how it explicity states that this provides the default for run steps, not uses steps. So I don't think this setting is meant to work for uses steps unfortunately, and I don't think there's anything we can do in this action to fix that.
