[5.5][Collections] Update CLI output for 'describe' (#3510)

* Fix CLI output for stars (#3439)

What we are displaying here are stars, not watchers, so the output should reflect that.

* [Collections] Include more package metadata in CLI output

Motivation:
The collection API implementation fetches additional package metadata via GitHub APIs but we aren't showing all of it in the CLI.

Modifications:

Add license and languages. Reorder line items. e.g., the updated output of `describe https://github.com/apple/swift-nio`:
