Add Support for JSONC (helix-editor#9906)

* Added `jsonc` language with support for comments

The `vscode-json-language-server` accepts `jsonc` as a language id.
Allowing the use of comments within JSON files.

* fix: Update `injdection-rejex` to be unique

* fix: use includes to remove redundant queries

* ci: Generate language-support docs
