feat: add lefthook, megalinter and update editorconfig (#270)
This change adds [LeftHook](https://lefthook.dev/) as a GitHub hook management tool alongside [MegaLinter](https://megalinter.io/) to lint all relevant files within the repository.

For users that don't end up installing LeftHook for pre-commit hooks, megalinter picks up the necessary formatting changes and reports them.

* feat: add lefthook, megalinter and update editorconfig
* fix: lint commit ordering
* refactor: adjust megalinter reporters
* refactor: adjust description for cache domains
* refactor: single - for passing options
* refactor: add repo-specific fmt in megalinter pre-commands too
