fix: enable python bytecode in the uv plugin

[jonathan-conder]

This brings the uv plugin in line with python (version 1 and 2) and poetry.

In snaps, launching python can still be slow by default because bytecode is not generated for the standard library when extracting stage-packages.

interesting, I had erroneously assumed this was the default
@lengau do you see any potential issues with this?

[lengau]

I don't see any issues with it. I think the reason for not doing this was to match the fact that the python and poetry plugins don't compile bytecode either.

[tigarmo]

I think the python plugin does this because pip does it by default? I might be mistaken though

Thanks for adding the changelog entry. While this can be seen as a bug fix I think it might be more appropriate as a new (minor) feature? I see some potential, if unlikely, breakage if two different parts use the uv plugin (pyc files will very frequently conflict in stage)

We might also add a sentence saying that one can use UV_COMPILE_BYTECODE=0 to disable this behavior.
