Pants reports tomllib as a unowned dependency for a Python 3.11.* IC.

Looks like:

05:56:35.60 [WARN] Pants cannot infer owners for the following imports in the target science/config.py:

  * tomllib (line: 4)

If you do not expect an import to be inferrable, add `# pants: no-infer-dep` to the import line. Otherwise, see https://www.pantsbuild.org/v2.15/docs/troubleshooting#import-errors-and-missing-dependencies for common problems.

The issue is ~by design from #13491 which freezes in a global list from Python 3.10. Either that list has to be added to, or, it seems better, the list should be generated by a rule that runs a Python Process using the target Python > 3.10 interpreter in-question when the interpreter in question is of version > 3.10.

I don't remember which (if any) modules have been removed from stdlib, but it might be safer to union the stdlib from ALL versions of Python to ward against removed modules.

EDIT: Oh you mean run a Python process in a rule on the user's behalf. Not a process to generate this static list? Yeah that'd work too. I'd +1 that.
