Update deployments for the hosted signaling server

[jacobheun]

The signaling server deployments are out of date, and haven't been deployed in some time. The deployment path for these needs to be improved and the latest version needs to be deployed.

I will be looking at getting this resolved soon, ideally before end of next week (June 21).

Now that we have a Dockerfile for this we need to work on getting a server deployed for folks to be able to dev on. Infra issue https://github.com/protocol/infra/issues/509
