Stop hardcoding exact versions in pyproject.toml

[C0rn3j]

pip check fails on my system because the project currently hardcodes dependencies to specific versions:

$ pip check
archinstall 4.4 has requirement cryptography==48.0.1, but you have cryptography 49.0.0.
archinstall 4.4 has requirement markdown-it-py==4.0.0, but you have markdown-it-py 4.2.0.
archinstall 4.4 has requirement textual==8.2.7, but you have textual 8.2.8.

The deps should all iirc be >= , to allow that version as a minimum one and any version coming after it.
Or stop defining a version altogether.

If you wish to provide a set of deps that the project is guaranteed to work with, use pylock.toml (or uv's own lockfile system) - https://packaging.python.org/en/latest/specifications/pylock-toml/#pylock-toml-spec
