Calling the public API endpoints will check for matching registered
reference providers that implement `IPublicReferenceProvider` and call
their respective functions. If no matching provider is found, the
default `LinkReferenceProvider` will be used to provide open graph data.
The frontend reference widget components will call these endpoints from
unauthorized sessions, e.g. in public shares.
If present, the sharing token of the origin URL is passed to
`resolveReferencePublic()` as additional information for the reference
provider to determine the access scope. This allows the respective
reference providers to determine whether the origin share has access to
the linked resource.
`getCacheKeyPublic` also gets the sharing token so it can scope the cached
entry to it.

This would be useful to eleminate the need for using this OC class
when an app dev wants to implement a custom reference provider
for the web client but wants to fall back on opengraph for mobile
clients.
