Missing syntax highlighting on LSP hover docs

[Yuuki1578]

Before helix 25.07.1, syntax highlighting on LSP hover docs require markdown and markdown_inline grammar.

I install the grammars using hx -g fetch and hx -g build on this languages.toml config:

use-grammars = { only = ["c", "markdown", "markdown_inline"] }

And that work just fine. In version 25.07.1 however, it just doesn't work again:

I'm trying not to install the helix-grammars package so i can build the grammars from source.
