add tree-sitter-embedded-template (erb & ejs) (#2055)

After the incremental parsing rewrite for injections (which was released
in 22.03 https://helix-editor.com/news/release-22-03-highlights/#incremental-injection-parsing-rewrite),
we can now do combined injections which lets us pull in some templating
grammars. The most notable of those is embedded-template - a pretty
straightforward grammar that covers ERB and EJS.

The grammar and highlights queries are shared between the two but they have
different injections.
