New tree sitter "official" langs

[Ergus <spacibba@aol.com>]

Hi:

Recently I have found that some of the grammar source repositories
we use in:

https://github.com/casouri/tree-sitter-module

are out of date (2 or 3 years with no updates, fixes or replies to
issues).

Some of those repositories are somehow "Legacy" because they are
superseded by a new "official" repository:

https://github.com/tree-sitter-grammars

This seems to be a meta-repo including support for many langs including
some that are supported by emacs.

I opened this issue:

https://github.com/casouri/tree-sitter-module/issues/53

Where I added a table of the modules that could be desirable to update
to the `tree-sitter-grammars' source. Most of them can (and apparently
should) be updated immediately with no issue.

The only two exceptions are markdown and scss, where we use two grammars
that seems unmaintained. So I may ask the *-ts-mode developers to
consider to update to the new grammars versions if there is some
incompatibility.

Specially the markdown one seems to be more feature rich and include
inline markdown as well. https://github.com/tree-sitter-grammars/tree-sitter-markdown

The scss looks like maybe in the past it was forked from the one we use,
not sure of this.

In any case, none of those two have been updated in 3 years and the new
version received updates only two months ago.

Best,
Ergus
