Consider moving from poetry to uv

[ItsDrike]

To follow the latest best / most recommended practices for python project packaging tools, we might want to consider moving to uv.

Previously, uv was just a pip alternative, but it has since been updated and became a full fledged tool for projects packaging & dependecy management. Uv is written in rust and is developed by the same people that work on the ruff linter & formatter which we're already using. It has proper support for all the needs that we currently have when it comes to dependency management, including built-in support for python version picking and dependency groups. Uv can also install the necessary python versions automatically (auto-downloading pre-compiled python binaries). The main advantage of uv would definitely be the speed increase though, which can easily be 10x faster in comparison to poetry.

To be fair, poetry is still not a bad choice and this isn't something that we'd have to quickly push for, but it may be a nice change to make as poetry grows less and less popular in favor of uv.

Note regarding #394: uv is more stable than Rye and even the Rye maintainers suggest using uv instead.
