How to sync ruff versions between rules_lint and venv

[TimotheusBachinger]

This is more or less a follow-up to #465
And it is more or less a question of "what is the best way to do XY"

Status Quo:

• we use rules_lint to ruff our python code base
• rules_lint pulls in a dedicated version of ruff (see e.g. https://github.com/aspect-build/rules_lint/blob/3845d04c68102b092c22d39f53d3c1839e514339/lint/multitool.lock.json)
• in our project, we also use rules_uv to generate a virtual environment for testing, type checking etc.
• the ruff version we get in the exported venv therefore most likely deviates from the one used by rules_lint (devs are more likely to use the ruff from the venv as it is integrated in their IDE - @alexeagle shows something similar e.g. in https://www.youtube.com/watch?v=GTsy7IfmywQ)

So we ask ourself - what is the recommended way to sync up those possible mismatching ruff versions?
