Using \* within the title regex appears to cause a failure.

Describe the bug

Using \* within the title regex appears to cause a failure.

To Reproduce

Using this config:

      - name: Check PR Title
        uses: clowdhaus/actions/pr-title
        with:
          on-fail-message: "Your PR title doesn't match the required format. The title should be in the conventional commit (https://www.conventionalcommits.org/en/v1.0.0-beta.4/) format. e.g.\n\n```\nchore: add pr title workflow\n```. Note that scopes should not contain spaces."
          title-regex: '^(build|chore|ci|docs|feat|fix|perf|refactor|revert|style|test)(\((\*|[\w|,|\-|\|]+)\))?(!)?\:\s.*'
          github-token: ${{ secrets.GITHUB_TOKEN }}

Attempt to validate a PR title of fix(*): use tsup (again) to produce compatible esm and cjs builds

Expected behavior

As evidenced by testing the regex manually:

/^(build|chore|ci|docs|feat|fix|perf|refactor|revert|style|test)(\((\*|[\w|,|\-|\|]+)\))?(!)?\:\s.*/.test('fix(*): use tsup (again) to produce compatible esm and cjs builds')

The regular expression is valid and the PR title provided as an example passes test. The workflow shouldn't be failing.
