Currently, including a tree-sitter parser as a dependency in a zig
project and running `zig build test` on the project will fetch the
zig-tree-sitter dependency declared by the parser. This is a problem
because (a) consumers may not want this dependency for whatever reason
and (b) due to how often Zig breaks everything and how scarcely most
tree-sitter parsers are updated, the zig-tree-sitter version pinned
by the parser module will often be outdated and broken.
The workaround I used was taken from https://ziggit.dev/t/11234
