[🙏] Add a collection

[lvstb]

Describe the user need
I want to be able to visualize a collections status via the plugin

Describe expected behaviour

If i add a collection to the config ex: snyk.io/collection: collectionid
It would be possible to see an overview of a collection instead of adding multiple projects one by one.

Ack. Does make sense indeed imo. Will try to slate that in asap
