Discover sharedInbox

It looks like Lemmy is currently assuming all instances have a sharedInbox at /inbox, which is not good. Per the AP spec, sharedInbox should be optional and is found in endpoints.sharedInbox on the Actor

That's only if their user doesn't have a sharedInbox, which all lemmy clients should at least.

In general you should always use sharedInbox for all public activities:

Connecting to non-lemmy clients is way down the road.

We still also have to store a few activitypub fields in the DB, which we aren't yet currently.

yeah, the "optional" part doesn't seem practically necessary, though it's technically required by the spec
