Updated web-tree-sitter and the devicetree grammar.
web-tree-sitter now supports a custom function to locate its .wasm file,
so performing a string replace is no longer necessary to get it to work
with Docusaurus' Webpack configuration. We now check when tree-sitter is
locating its .wasm file and provide the Webpack-adjusted URL.
Bumped web-tree-sitter to v0.19.4 and added v0.4.0 of
tree-sitter-devicetree, which had to be rebuilt to work in v0.19.x
https://github.com/joelspadin/tree-sitter-devicetree/releases/tag/v0.4.0
Changed how we patch web-tree-sitter to correctly load tree-sitter.wasm
to work with the latest version of Docusaurus. Including a copy of
tree-sitter.wasm as a static resource is no longer needed.
