Create additional labels when detecting Dendrite or Conduit homeserver

This should make it easier to spot rageshakes related to users running these homeservers. Currently the server_version field is only sent by Element Android though so will need to do something about iOS still.

Some of the formatting is due to running goimports on submit.go so sorry about the noise with that.

Keep in mind clients have no CS API to ask the server for its version, that's on the federation API only https://spec.matrix.org/v1.2/server-server-api/#get_matrixfederationv1version so is unlikely to get implemented across the board as it'll be brittle due to some clients (web) being unable to perform the SRV lookups required to locate the federation API for a given server

Bah, of course. That's annoying.

yeah, I'm a bit 👎 on this change. It feels like it's going to be fragile.
