Feature request

Is your feature request related to a problem? Please describe.
I think the Snippets in the sidebar of the template editor (vs code) are outdated.

Describe the solution you'd like
It would be nice if these were updated for RazorTyped and all that, with some updated examples for looping items and getting module and tab and portal info and what not.

Describe alternatives you've considered
No alternatives.

Additional context
I still use Snippets quite a bit, even if it's just to give me a hint. But it would be nice if these were up to date so that people like me could stay more up to date with how to do thing in RazorTyped.

I should mention - it would also be great to remove the really old stuff or the methods that people shouldn't be using so we can trim down on it. All killer, no filler :)
