feat: re-enable haskell syntax

[billksun]

Updated tree-sitter-haskell to tree-sitter/tree-sitter-haskell@bf7d643, and everything compiled. Also verified that syntax highlighting for Haskell is working on NixOS.

The problem was cross compilation to aarch64. I don't think that's easily solvable unless cargo-cross is updated to a newer GCC version. tree-sitter/tree-sitter-haskell#34 (comment)

Yeah, they have new instructions for building on MacOS: https://github.com/tree-sitter/tree-sitter-haskell#building-on-macos

From tree-sitter/tree-sitter-haskell#46

[archseer]

Yeah, I had it building on macOS on CI previously. The issue is getting aarch64-linux to compile.

With

helix/helix-syntax/build.rs

Lines 61 to 65 in e042121

	let flag = if build.get_compiler().is_like_msvc() {
	"/std:c++17"
	} else {
	"-std=c++14"
	};

it compiled on macOS

From the last 2 comments here, tree-sitter/tree-sitter-haskell#34 (comment), it seems like using the Homebrew GCC from a M1 Mac will get you the correct version of GCC. But I see what you are saying now, we need the cross-compiler support to be on the right version as well.

It might be okay to disable aarch64-linux builds altogether and disable cross compilation. Not sure how popular these builds are.
