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

It looks like this workflow, [.github/workflows/parse-issues.yml](https://github.com/adoptium/aqa-tests/blob/master/.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`

Start with .github/workflows/parse-issues.yml at line 29 and inspect how exclude_files.txt is generated. Check the workflow's file selection around openjdk/excludes/vendors, then run the parse_issues workflow or its referenced command. Done means the vendors directory is not treated as a file and the workflow completes successfully.
