[bug#60240] [PATCH v2] gnu: Add python-3.12 and python-next.

[Lars-Dominik Braun <lars@6xq.net>]

Hi,

LGTM.

I believe the separate tk output does not give us any benefits regarding
closure size (any more?), because tcl and tk are both referenced from
`out`. Can we remove those references to reduce closure size again?

And I can also confirm test_asyncio runs out of memory on my machine
and test_threading never finishes. We should probably investigate both,
because they should not.

Line 641, as highlighted by `git show`.

> Btw, the patch targets the branch `python-team`.

I believe this change could target master, since it only adds python-3.12,
but does not cause any rebuilds using it.

Cheers,
Lars
