doc comments don't work on types in new solver

[jackdotink]

type foo = {
	--- foo bar baz
	field: number,
}

local a: foo

a.field -- this gives the information "foo bar baz" when using the old solver, but the new solver gives nothing

[checkraisefold]

I am fairly sure that the new solver and old solver in fact do not provide this info, in which case this should be closed
luau-lsp does with its own solving, and the implementation for it is broken with the new solver - which is getting fixed shortly (hopefully) with my PR
