fix: removed unused keyword

[DerekStride]

What

fixes #155

Use the keyword_language node in the grammar rules.

[DerekStride]

@matthias-Q I'm requesting another review, I added some more commits that ensure our keyword_ nodes are in sync with the highlights.scm file.

You can see the failure message here: https://github.com/DerekStride/tree-sitter-sql/actions/runs/5456777435/jobs/9930044879

And see it fixed in the latest commit.

I am bit short on time today. I can take a look tomorrow. I was noticing a lot of "new" keywords in the highlights. Did we missed all of them? Do we need to add them to nvim-treesitter as well? If so, I would maybe put some of them not under the @keyword query.

yeah they were all missing & need to be synced to nvim-treesitter.

I would maybe put some of them not under the @Keyword query.

I moved a few of them to @attribute, there's still a lot of generic @keywords but I'm not too sure where else they could belong

[matthias-Q]

Looks good. I made two suggestions for the highlights, but in the end I expect the maintainers of nvim-treesitter to have their own opinion 😄

[matthias-Q]

float can be a @function.call and a @type.builtin

select 
 1::float;

select 
 float(1);

So I would keep it there. in nvim-treesitter - the last match wins, thus the order matters here (which makes things unnecessarily complicated imo.)

[DerekStride]

We already have float in @type.builtin and the rule for invocation should cover the @function.call case.

[matthias-Q]

I think statistics and stats should be @type.qualifier and not @keyword

[DerekStride]

I removed these from here because they were duplicated in @type.qualifier already 👍
