TL;DR

The readme states that install_components should be a "List of Cloud SDK components to install" but it appears that a comma-separated string is expected rather than a list.

Expected behavior

I would expect to be able to use a YAML list to specify the install_components input.

Observed behavior

If a YAML list is used to specify the install_components input such as install_components: [beta, cloud-datastore-emulator], the following error is produced:

The workflow is not valid. .github/workflows/test.yaml (Line: 17, Col: 9): A sequence was not expected

But using a comma-separated string such as install_components: beta, cloud-datastore-emulator works.

Action YAML

name: Test
on: [push]
jobs:
  test:
    runs-on: ubuntu-20.04
    steps:
    - name: Set up Cloud SDK
      uses: google-github-actions/setup-gcloud@v0
      with:
        install_components:
        - beta
        - cloud-datastore-emulator

Additional information

Perhaps this is expected behavior, but if so it seems to contradict what's written in the readme.
