Adding typehints

[thomaszwagerman]

Adding typehints throughout MeshiPhi.

Making changes where required by mypy (can also be called with make type-check), ensuring ruff check and pytest also all pass.

Adding in types-jsonschema to the [dev] requirements to allow typechecking of config_validation module (heavily uses jsonschema). See typeshed. There are still a lot of libraries we are ignoring, but this makes sure we don't have to ignore the whole config_validation module.

(also a small github actions/ version bump)

I'm a bit confused at github-pages-docs being the merge target here?

Double check the min time handling in ERA5 loaders (e.g. era5_wave_direction_vector.py)

Saving this for a branch working on dataloaders specifically

Converting back to draft.

Changing cellbox id's from str to int is changing the results. Things like iteration order behaviour through the neighbor graph dictionary or floating point precision could be the source?

What the "correct" approach is might need to be determined by Jonny.
