feat(plugins): list Career Coach in the plugin catalog (protoLabsAI#1765)

Adds the careercoach official plugin (https://github.com/protoLabsAI/careercoach-plugin)
to config/plugin-catalog.json + the marketing sites/marketing/data/plugins.json mirror, so
it shows in System → Plugins → Discover for one-click install alongside the other plugins.
