Interest in adding a Nix flake definition in this repo?

Firstly, thanks for this language server!

I have just starting using it successfully with Helix.

My setup is all Nix based, so I wrote a Nix flake to build and consume this language server in my config. It makes the setup very straightforward for anyone who has Nix (which is highly recommended 😉)

Is there any interest here in a PR to add the Nix flake to this repo? IMO better to have these things with the source, rather than separately as now. I would envisage contributing a wrapper script for gradle2nix to keep the gradle.lock file up to date when things change here. This would mean adding the three files from my Nix flake repo, and I would extend the flake.nix to have the wrapper script support, so minimal extra baggage for those with no interest in Nix.

Thoughts?
