🎨🚨 Improved formatting and linting config

[burgholzer]

Description

This PR adds a couple further pre-commit checks and other utilities to ensure the validity of certain configs. This includes:

• a pre-commit check for checking several schemata for their correctness, such as dependabot and GitHub actions
• an .editorconfig file for enabling wide spread support for proper formatting out of the box
• a switch from codespell to the typos spellchecker that is more comprehensive and a lot faster
• a validate-pyproject check that makes sure the pyproject.toml is valid
