Auto label PR's

[gonX]

There are some labels which in some cases can easily be applied based on files changed:

Label	Path
ci	/.github/workflows/*
documentation	*.md in root except index or docs(?) folder
linting	need to compile a list, but linter.yml and some other config files
meta	**/*.sh, /.github/*, /.*, more?
styling	usually assets/ but with exceptions?
wiki	/_wiki/*

Some consideration has to be done as to whether we should use the labels this well-defined, or if such strict label usage should be kept to a minimum, e.g. #65 technically has styling changes but it shouldn't actually affect styling.
