11.4.0 - Hello 2022!

This is a big one. Holidays and all. Wishing all of you the best for 2022! See the note below about theme changes if you're super picky about your theming.

New Languages:

• Added 3rd party Pine Script grammar to SUPPORTED_LANGUAGES Jeylani B
• Added 3rd party cURL grammar to SUPPORTED_LANGUAGES highlightjs-curl

Themes:

• Default is now much closer WCAG AA (contrast) (#3402) Josh Goebel
• Dark now meets WCAG AA (contrast) (#3402) Josh Goebel
• Added intellij-light theme Pegasis

These changes should be for the better and should not be super noticeable but if you're super picky about your colors you may want to intervene here or copy over the older themes from 11.3 or prior.
