Multi-ID package tracking for releases site

Repo: Jumoo/releases

Added aliasNugetIds support to data/packages.json so renamed/rebranded packages (several Translation Manager connectors, GlobalLink) keep their full NuGet download and version history merged under their current package ID
Added a JSON Schema (data/packages.schema.json) for packages.json plus VS Code wiring for editor autocomplete/validation
Renamed several Translation Connector titles to a shorter "X Connector" style and fixed LanguageWire's githubRepo (was pointing at the GlobalLink repo)
