[GH Request] Flaky edx-platform builds due to docker rate limit

Problem/Request

The following edx-platform build failed with a flaky docker issue: https://github.com/openedx/edx-platform/actions/runs/12775202089/job/35611041323

Starting single-node instance, no replica set
    - port [27017]
    - version [7.0]
    - database []
    - credentials [:]
    - container-name [mongodb]
  
  Unable to find image 'mongo:7.0' locally
  docker: Error response from daemon: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit.
  See 'docker run --help'.
  Error starting MongoDB Docker container

Reasoning

For 2U, this kills our deployment. For others, any flaky issues are an annoyance, having to re-run tests simply to prove that PR is in fact working.

Thank you for your report! @openedx/axim-oncall will triage within a business day. Simple requests usually take 2-3 business days to resolve; more complex requests could take longer.

Note: This also happened on the Jan 6: https://github.com/openedx/edx-platform/actions/runs/12639140889/job/35216834568. This also happened on Jan 9 from our notes, but no link.

This just realized this is a duplicate of another (closed) ticket, since we thought the earlier issue was fixed:

• [GH Request] CI checks failing due to Dockerhub rate limiting #1350

Closing in favor of working from the original ticket #1350
