python39Packages.virtualenv -> time-machine-2.15 -> "Python 3.9 not supported"

[suntropez]

Within a Nix REPL of 24.11:

nix-repl> pkgs.python39Packages.virtualenv

error: time-machine-2.15.0 not supported for interpreter python3.9

This commit has this changeset:

-  disabled = pythonOlder "3.8";
+  disabled = pythonOlder "3.10";

However, upon consultation of both the package in PyPI and the project home I'm left to believe 2.15 should be fine with 3.8. The next version drops support for 3.8 but retains for 3.9.

I can PR the partial revert, however, something tells me there might be more to this 🤔

Someone else seems to have stumbled on this too.

I disabled it for Python <= 3.10 to get rid of backports-zoneinfo which is required for Python 3.9 and older.
