@internal attribute not handled correctly

[SpyrosRoum]

Hello, it looks like using @internal is not currently supported. The most obvious effect of this is syntax highlighting breaking from the attribute forward:

One Interesting observation is that if I add parenthesis to the attribute, it works fine, but this is wrong and gleam fails to compile:

I am not sure if this might be an issue for tree-sitter, please let me know if that's the case.
I did check the tree and (attribute @ name: (identifier)) is recognised by tree-sitter, which seems correct to me, though I know little about ts:

Edit to add info:

• I am using doom-emacs, so not the build in tree-sitter.
• Emacs version 30.0.50
• I have the latest version of the grammar, which is also the one pinned in this repo.
• I am on tree-sitter version 0.22.5
