Fix the invalid path on Windows when loading the treesitter wasm file

Example

 no such file or directory, open 'C:\C:\.....\target\spotless-prettier-node-modules-a419b185f88f4c8243af8729ce04d5c8\node_modules\prettier-plugin-java\dist\tree-sitter-java_orchard.wasm'

Thanks for the contribution (and inherently reporting this issue)! Unfortunately, this breaks use of this plugin in web (as can be seen by the failed GitHub Pages CI job). We purposefully omitted use of Node.js-only libraries for this reason. I will see if there's another way we can resolve this issue.
