Support workspaces in `uv version`

[AsafMah]

Summary

Currently (as of version 0.7.6) the uv version command does not support workspaces.

Meaning, that unlike most commands, it doesn't include the package and all_packages flags.
I think that it should, for consistency.

Furthermore, it would be nice to not have to re-specify the version on every project on the monorepo, and have them all automatically be synced to the root version.

This is mostly fixed by the current version of #13317, although --all-packages isn't included (uv add and uv remove don't have that flag, although it's more plausible for uv version).
