WIP Zed extension to add support for Cucumber/Gherkin.

Gherkin Tree-Sitter Grammar (via thlcodes/tree-sitter-gherkin), including
- highlights
- injections (for docstring)
- outline
LSP (via @cucumber/languageserver)
- looks for global executable cucumber-language-server first, installs/uses latest package @cucumber/language-server otherwise
- supports configuration via project setting, e.g.
```
{
  "lsp": {
    "cucumber": {
      "settings": {
        "glue": ["src/**/*.ts"]
      }
    }
  }
}
```
- Hint: currently @cucumber/language-server uses a node-tree-sitter version that does not support Node 19/20
