Maintenance: Switch to Poetry v2

[twwd]

Use Poetry v2 in the GitHub action and use newer pyproject.toml structure.

[IV1T3]

Or switch to uv? https://github.com/astral-sh/uv

Personally, I'm happy with Poetry and like the concept that the package manager is written in Python itself.
On the other hand, we are already using ruff from Astral that is also written in Rust.

What are the advantages of using uv from your perspective?

@IV1T3 Do you have good reasons for the change?
