Add &| and 2>| as pipe operators

[piechologist]

Currently, both operators result in errors in the syntax tree.

This PR adds two convenience pipe operators (see the fish docs) discussed in #20:

echo Piping &| cat
echo Piping 2>| cat

I changed both grammar.js and grammar.ts to be able to build the parser locally. The added tests pass using tree-sitter 0.22.2.

I added the operators to highlights.scm as well.

Closes #20.

Oops, looks like an old node version in a GH action? I tested with node v21.7.1 on my local machine.

Node should be fine, you're free to upgrade - it's not a big deal.
Error in pipeline comes from @types/node package.
Adding "moduleResolution": "nodenext" to tsconfig.json fixes errors.

This package could be removed by adding single ts-ignore above module.exports in grammar.ts 😅

Looks fine ;) Also please include auto generated files from src directory - so that the source is ready to use with your patch applied.

Adding "moduleResolution": "nodenext" to tsconfig.json fixes errors.

That did the trick. I've neither upgraded node nor added ts-ignore. Didn't want to touch so many things at the same time 😉

I've also incorporated #22 (drop ^).

Then ran tree-sitter generate && tree-sitter build locally with the latest tree-sitter v0.22.2. That's what homebrew gave me. So, those files went into src.

Thanks for being patient 😃.
