* The build status badge is now for GitHub Actions.
* The documentation now mentions GitHub instead.
* Warnings in the YAML file have been fixed or ignored.
Prior to #3448, several linters should have been failing the
custom-checks that look for non-snake-cased lint names. They weren't,
but now the bug that hid those is fixed. So to avoid breaking users, we
just exclude those from the check. Linters excluded:
* clojure/clj_kondo.vim
* elixir/elixir_ls.vim
* go/golangci_lint.vim
* swift/swiftformat.vim
* The project style linter now runs while you type.
* Now the scripts for checking the project require blank lines.
* Many style issues have been found and fixed.
