_python* packages: do not use Python 3.9 as "defaultVersion" anymore. (#12589)

While switching to 3.10 as default, lets just drop the 3.9 versions of these packages.

----

Checked runtime and build dependencies, but only tried a build of `hatchling` locally. I'll merge as is, and if something breaks, will fix later on.
