Add option --exclude to audit-translations

[CristianCantoro]

Hello, I am going over the instructions for validating new translations and I have found useful to add an --exclude option to audit-translations.

This option allow excluding specific files from the audit. In a sense, it does the opposite of what --file does, but --file can be used to specify only a single file.

I have added the following examples in the README.md:

# Exclude a list of files from the audit, note that if you use this option before specifying the
# target language you'll need to use the option terminator (--)
uv audit-translations es --exclude unicode-full.yaml
uv audit-translations es --exclude unicode-full.yaml unicode.yaml
uv audit-translations --exclude unicode-full.yaml -- es

sounds good to me. @TimArborealis @AndersEkl what do you think?

@michaldziwisz what is ipdb used for? I've not heard of that package before.
https://pypi.org/project/ipdb/ says it gives access to the IPython debugger, so do you use that in a Jupyter Notebook, or can you run the IPython shell by itself (also haven't done that ever now that I think about it)?
