The 'athens-proxy' build step in drone should build an Athens image and run it, instead of using the canary image

[arschles]

Describe the bug

Since we're using the canary image, we are running the Athens server was built from the previous merge to master. That might be useful, but I think it's more useful to run the current one and test against that.

This might be tough to do in drone, since we need to run Athens as a service. Not sure if we could do it in GH actions (#1460) either...

We could possibly build and run an Athens container (we currently only run it as a process in the background) as part of e2e tests (#1474)
