refactor(ci): Split docker run into launch, logs, and wait

[teor2345]

Motivation

This PR further splits up the docker run job.

It is part of ticket #4661.

Solution

This PR splits the docker run jobs into 3 different jobs:

• launch: docker run --detach
• logs: docker logs --tail all --follow
• result: docker wait

It also fixes up some comments and formatting.

Review

This might be one for Gustavo, but anyone who understands GitHub workflows and docker should be able to review it.

Reviewer Checklist

• All GCP workflow jobs have launch, logs, and result steps
• Failing jobs still fail

Follow Up Work

• split the logs into checkpoint (sprout, sapling, orchard?) and full validation (sapling?, orchard)
• require that full sync goes to 100%

[teor2345]

I'm running full checkpoint and tip syncs here:
https://github.com/ZcashFoundation/zebra/actions/runs/2566077841

They seem to have the right jobs, but we still need to check the jobs run correctly before we merge.

Looks good! But @gustavovalverde might want to take a look later just to double check.
