Can this project be revived?

Hi. I recently created [a JetBrains plugin for Xonsh shell scripts](https://github.com/nahoj/xonsh-jetbrains). The plugin mostly wraps [xonsh-lsp](https://github.com/FoamScience/xonsh-language-server) (using LSP4IJ) which relies on [a TreeSitter grammar](https://github.com/FoamScience/tree-sitter-xonsh).

I'd be interested in using this TreeSitter plugin in combination with mine to provide syntax highlighting when the LSP is not in use (diffs, xonsh files while xonsh-lsp is starting, etc.). Indeed, it would make syntax HL consistent from both sources, and maybe I could make the TreeSitter plugin back off when the LSP is running, to avoid duplicating semantic tokens.

However, this project doesn't build for recent versions of JetBrains IDEs.

Would you be willing to update the build system, or merge a PR if I did?
