feat: use treesitter Query for building Positions

[cristianoliveira]

Playing with the tree-sitter is quite fun :)

I figured tree-sitter comes with a built-in query feature, I'm not sure it is more performant than the current implementation, I didn't test it, but I'd place my bet on that.

I used this for reference:
https://tree-sitter.github.io/tree-sitter/using-parsers#pattern-matching-with-queries

Also their unit tests https://github.com/tree-sitter/tree-sitter/blob/master/cli/src/tests/query_test.rs

I didn't remove the dead code, I just kept it as a comparison, but accordingly with the tests, they are behaving the same. This implementation also contains the fix for #11

This implementation doesn't address the suggesting when editing an attribute in the middle of other hx-*
For instance:

<div hx-get="/foo" hx-target="<cursor here>" hx-swap="next"></div>

you are freaking awesome

i love queries (i just didn't want to have to relearn everything for them) this looks perfect.

the tests look great and the queries look great too
