completion.menu.draw.treesitter should only affect items from the LSP source

Feature Description

Just discovered the feature, and I quite like it. However, by applying it to all items, you also get a lot of spurious highlighting of words such as in or file, often used for example in names of snippets.

I think limiting the highlighting to items from the LSP source only would produce the best result by highlighting the correct things, while not highlighting things that are not are nor code.

For anyone looking to implement this, the treesitter option should be changed to accept a table of source_ids that it applies to. The documentation should then recommend treesitter = { "lsp" }
