incorrect github action matrix description

[jeromedockes]

some errors in the 'include' value here:

• the dependencies-version min-py310 only has effect on the python 3.10 environment, so other jobs listed as "with minimal dependencies" actually use the latest versions of the dependencies. that may be relevant @jovan-stojanovic when you look into the fetch ken embeddings failure on macos with python 3.11 and "minimal" dependencies -- check the actual versions used in the log they are the most recent
• the "dev, polars" for py 3.11 overwrites dev, pyarrow so the latter is never used
