sagemath-standard: Add missing dependency typing_extensions, set lower bounds for backport packages

[mkoeppe]

Used in src/sage/dynamics/arithmetic_dynamics/projective_ds.py.

We also set lower version bounds for backport packages importlib_resources, importlib_metadata, typing_extensions so that Sage developers can use Python 3.11 features.

Actually the import seems unused in that file, but it's good to have this backport package as a dependency as preparation for more type annotations.

Replying to Matthias Köppe:

I can't say I have any idea why I added this import. It seems like it can (and perhaps should) be removed.

I've opened #34859 to remove it.
