Haskell syntax highlighting regression

[mmaa]

Summary

Syntax highlighting in Haskell no longer works. I believe the regression may have been introduced in #13475.

Reproduction Steps

Open any Haskell file since the aforementioned Haskell tree-sitter update was merged. I don't get any syntax highlighting in any Haskell file.

An error like that is printed when your parser and queries are out of date with one another. You can run hx -g fetch and hx -g build to build the newer version of the parser which should recognize the updated highlights.
