[ENH] - use -V instead of -v as shortform for --version

[pmeier]

Feature description

Per title. In the Python ecosystem, -V (upper case) is usually used to display version information:

❯ python -V
Python 3.8.16
❯ pytest -V
pytest 7.2.2

-v (lower case) is usually reserved --verbose, which we currently don't have, but maybe will have in the future.

Value and/or benefit

Consistency lowers entrance burden.

Anything else?
