Bumped to 2.21
I dropped editorconfig-core-py and python3-jsbeautifier because 1) I don't use that feature so it would be guaranteed to break without me noticing 2) the docs list the [optional dependencies](https://urlwatch.readthedocs.io/en/latest/dependencies.html#optional-packages) 3) It's probably easier to install it via pip
