[docs] Add TS Docs

[e111077]

Currently having trouble integrating TS into rocket. Is it supported?

Would appreciate some documentation on how to do so

*.rocket.[js,md,html] will not support Typescript for now... those files should mostly be about content...

but yes indeed you should be able to write your components and templates in ts - not 100% sure how but I assume something with esbuild...

probably will become a dedicated "preset" so you can enable it with one npm install and one line in the config
