Set the version in pyproject.toml instead of having it dynamic (#706)

* Set the version in pyproject.toml instead of having it dynamic

This reduces complexity of the build and should allow us to use
dependabot with uv. Also standardizes releases a bit more as the version
isn't hidden anymore in the __init__.py file

* Run uv sync to make pre-commit happy

The uv lockfile is now on version 2

* Don't try to include a file that doesn't exist anymore in the decision container
