feat: Add Airflow 2.10.2 to tests

[NickLarsenNZ]

Part of stackabletech/docker-images#847

Add Airflow 2.10.2 to tests and docs (except getting_started).

Note

@sbernauer and I discussed whether the experimental version should be listed as latest, or even included in the general test run. We decided on adding it, and if it proves problematic, we can remove it again.

Description

Please add a description here. This will become the commit message of the merge request later.

Yes it is ready for review. I purposely left it out, but I can add it in and put (experimental) next to it?

Done in 7f5ce5f.
I left getting_started at the LTS version.
