Fix docker hub isssue for e2e tests

[njogz]

The e2e Github action is failing as seen here due to too many requests to Docker Hub. A solution is to use the organisation account which has a higher limit on the amount of requests that can be made.

@njogz Is this issue resolved now?

[njogz]

@craig-landry not yet. The action is still failing.

I had a look at this and it looks like we're using Medic's AWS instance for the CHT images but we're still pulling a whole lot of third party images from docker hub. If possible we could publish these to AWS or potentially look at caching the images somehow. Another alternative would be to add some delayed retry so it installs eventually.

I have a similar issue (see attached); having too many requests though the logs on this PR have expired. Here is the PR with the error in the GH Actions.
