Migrate to Pydantic v2

[ChrisLovering]

Summary

All commits starting with breaking: are breaking changes from Pydantic and will be squashed into 1 commit before merging. (Hence the do not merge tag)

Other commits are kaizen style commits that I noticed while working on this PR.

This will be far easier to review commit-by-commit.

Todo:

Squash commits before merging

Required investigation
I have not investigated if @field_validator("", mode="before") works the same as @validator("", pre=True) as far as the "*" is concerned to run the validator on all fields. relevant commit: 46bf3cc

According to their docs, it looks like a wildcard will do the job.

Great work.

Would you like to do the same thing as 3a279b3 for Colours and Emojis, I don't think these are things that anyone will ever configure, i don't even see the use of configuring them. (Might as well look into other classes that we ourselves do not quite setup)

I didn't touch colours as it has the validator, but that just seems to convert hexstrings into ints, so that might be something we can move to a basic class. Emojis needs to stay he same way as it is, mostly for the trash & incidents emojis.
