Collection CI related actions needed

[Andersson007]

SUMMARY

Relates to ansible-collections/news-for-maintainers#24.

It's been detected that this repository contains ignore-2.14.txt file but not ignore-2.15.txt file.

Actions needed:

• Copy tests/sanity/ignore-2.14.txt to tests/sanity/ignore-2.15.txt otherwise the CI will get failing.
• If it's not done yet, add the stable-2.15 branch to your CI workflow files. If you use GitHub actions, see the content of .github/workflows or, if you use Azure Pipelines, community.postgresql/.azure-pipelines/azure-pipelines.yml. If not added, this will violate the Collection Requirements for collections included in the Ansible package.
• Subscribe to and track the news-for-maintainers repository if you're not subscribed yet.
• If it's not relevant for this repo, just close the issue.
