Support of Google Sheets sintax

not really, it’s not an often used “language”. but it should mostly be covered by the generic highlighting mode.

if you want to implement your own highlighting support, take a look into the docs: https://github.com/EnlighterJS/documentation

there’s no difference between inline and block mode. in case the generic highlighting engine detects the elements as single tokens it should be possible using the theme customizer (but this will break all other languages)
