parse_issues workflow is failing with 'openjdk/excludes/vendors' is not a file

[smlambert]

It looks like this workflow, .github/workflows/parse-issues.yml, has been failing for the last 6 months.

Need to check, but may be a matter of updating this line: https://github.com/adoptium/aqa-tests/blob/master/.github/workflows/parse-issues.yml#L29 to ls -1dq openjdk/excludes/** | tee exclude_files.txt
