Add TextMate extension recommendation to the Language template

[RedCMD]

Hello allo 👋
I'm the owner of the TextMate extension tmlanguage-syntax-highlighter
I was wondering if you would be willing to add it to the extension recommendations in the Languages template (syntax highlighting)

I strongly think it'll be a great help for first time people trying out TextMate grammars
The main features it includes are syntax highlighting, intellisense, diagnostics and definitions

I see the js/ts templates have some recommendations

I'm happy to change anything on my end if need be
