[BUG]: data did not match any variant of untagged enum Trigger

Pre-submission checks

• I am not filing a feature request. These should be filed via the feature request form instead.
• I have looked through the open issues for a duplicate report.

Expected behavior

I expected zizmor .github/workflows/pull_requests.yaml to provide me some useful feedback on the action.

Actual behavior

It fails with:

failed to register input: .github/workflows/pull_requests.yaml

Caused by:
    0: invalid GitHub Actions workflow: file://.github/workflows/pull_requests.yaml
       
       Caused by:
           data did not match any variant of untagged enum Trigger at line 7 column 1
    1: invalid GitHub Actions definition: file://.github/workflows/pull_requests.yaml
       
       Caused by:
           missing field `runs` at line 7 column 1
    2: failed to register input as workflow or action

Reproduction steps

2. Run zizmor .github/workflows/pull_requests.yaml

Logs

Additional context

It might be related to #646 (shows the same error, but on invalid workflow).

Hi @nijel, thanks for the report! I'll triage this in a bit.

Ah, looks like this is similar to the underlying factor in #646 -- GitHub documents types: as being a list of trigger subtypes, but it can also be a scalar value. The JSON Schema in SchemaStore similarly suggests that it needs to be a list, so that's another bug there.

This is a pretty simple fix on zizmor's end, however!

This is fixed with #653. I'll also report it to SchemaStore in a bit.
