Latexplotlib

- update `lpl.subplots` docstring
- typing: allow both floats and ints as widths and height

Development
- remove unused packages from environment.yml
- add requirements.txt

- improve docstring of `lpl.suplots`
- improve logic of `lpl.subplots`
- improve tooling:
- add yaml formatting to pre-commit
- add other minor pre-commit hooks

- add dependabot for github workflows
- add mypy-lsp config
- fix previously unnoticed ruff errors

Highlights

This release exports all functions in `matplotlib.pyplot` to `latexplotlib`. This means you can use `lpl` as a drop-in replacement for `plt`and you don't have to import `matplotlib.pyplot` if you import latexplotlib. Also, there is finally a changelog 🎉

Code
- export `plt` functions in latexplotlib
- test new behavior and test that no functions beside `plt.subplots` are overridden

Readme
- update to reflect `plt->lpl` changes
- add changelog
