Fail to parse with rule `yaml.github-actions.security.curl-eval.curl-eval`

[lahabana]

Describe the bug
I get a syntax error on this rule when parsing valid github actions files:

Syntax error at line target.yaml:7:
 When parsing a snippet as Bash for metavariable-pattern in rule 'curl-eval', `${{` was unexpectedEngine(PartialParsing)

To Reproduce
Steps to reproduce the behavior:

1. Go to playground for this rule
2. Paste the minimal repro:

name: wf
jobs:
  create-release:
    runs-on: ubuntu-latest
    steps:
      - id: create-release
        run: |
            ${{ env.PRERELEASE_FLAG }} ${{ env.LATEST_FLAG }}

Expected behavior
Should pass (there's not even a curl in here :))
