ansible-core’s `devel` and `milestone` branch versions have been bumped to 2.21.0.dev0. If you are a collection maintainer, you need to consider:

1. If you test against `devel` or `milestone` and have a `tests/sanity/ignore-2.20.txt` file, you need to copy it over to `tests/sanity/ignore-2.21.txt`;
2. Update your CI matrix to include `stable-2.20` if you didn’t do that already; if you did not test against `devel` before, potentially need to create a `tests/sanity/ignore-2.20.txt` file.
