vscode-extensions.rust-lang.rust-analyzer: move to buildNpmPackage

The existing node2nix-based build was broken with #382557. I could not
salvage it, however apparently it is considered the deprecated way of
building node packages in nixpkgs.

This commit moves rust-analyzer’s vsix build to buildNpmPackage.

Fixes: #382845
Part-Of: #229475
