Release for Finagle 22.7.0 and 22.12.0

Feature

Please release versions of zipkin-finagle compiled with Finagle 22.7.0 and 22.12.0

Rationale

When running zipkin-finagle-http (compiled against Finagle 22.4.0) with Finagle 22.7.0, we see errors like

java.lang.AbstractMethodError: Missing implementation of resolved method 'abstract com.twitter.finagle.Status status()' of abstract class com.twitter.finagle.ServiceFactory.

due to twitter/finagle@b2a7f4e.

Finagle 22.7.0 was merged in #116, so I'm hopeful it would be straightforward to release that without further changes.

Finagle 22.12.0 hasn't been merged yet. Its PR is #123, and it looks like it's failing in CI, so that would have to be resolved, but I don't think that would stop releasing 22.7.0 at least.
