Add support for more languages (#69)

* Contain language selection dialog in an element that can be scrolled, and automatically scroll it if needed when navigating the list with arrow keys

* Add support for more languages:

Clojure, Erlang, Golang, Lezer, Ruby, Shell, YAML

* Move prettier auto format settings for languages into Language() class

* Remove invalid import

* Fix bug that could cause auto formatting to fail for the last block.
Add tests for language auto detection and formatting.

* Fix broken tests

* Fix language auto detection on Safari Webkit which was broken

* Remove unnecessary wait time
