Add more tests to the repo

This is a follow-up from the conversation in tree-sitter/tree-sitter#3348.

@liamwh would you be able to review this PR?

The only test that doesn't seem to work out of the box is this one:

world foo {
    include wasi:io/my-world-1 with { a as a1, b as b1 };
}

The issue is with the my-world-1.

In my parser, I've defined an identifier like this:

identifier: $ => /%?[a-zA-Z][a-zA-Z0-9-]*/,

Whereas your identifier is more sophisticated and enforces kebab-case where each "word" can't start with a digit:

tree-sitter-wit/grammar.js

Line 59 in 3d6124c

id: $ => /%?(([a-z][a-z0-9]*|[A-Z][A-Z0-9]*))(-([a-z][a-z0-9]*|[A-Z][A-Z0-9]*))*/,

I checked WIT.md and it doesn't explicitly give a regex for an identifier, but apparently it's meant to match the "label" production from the Component Model, which defines it like this:

label         ::= <fragment>
                | <label> '-' <fragment>
fragment      ::= <word>
                | <acronym>
word          ::= [a-z] [0-9a-z]*
acronym       ::= [A-Z] [0-9A-Z]*

Great work! Thanks for your contribution!

Great PR @Michael-F-Bryan! Thanks for this contribution! 👍

Please re-generate the parser.c file by running just test with a version of tree sitter ~0.22.6 and resolve the conflicts with the grammar.js, unfortunately I've added comments that caused conflicts with your PR. Apologies for that! 😅

Regarding the ID regex: I don't see the issue with the id matching showing up in tests, so unless I'm mistaken, it appears we don't need to do anything with that regex at this time?

Cheers,
Liam
