[GitHub Actions][Docker] Update Docker scripts & GitHub Actions to use ghcr.io instead of docker.io

[tdonohue]

References

• This is a port of both [Docker] Use fully qualified image names & allow for other registries to be used DSpace#10080 and [GitHub Actions] Refactor Docker build process to use ghcr.io for build, and then copy to docker.io once build completes DSpace#10120 to DSpace/dspace-angular
• Fixes DockerHub is throttling all DSpace image builds causing relatively frequent Docker build failures in GitHub Actions DSpace#10092 for dspace-angular

Description

This small PR updates the following:

• Changes all Dockerfiles and Docker Compose scripts to use fully-qualified registry names & to support alternative registries (like ghcr.io). See [Docker] Use fully qualified image names & allow for other registries to be used DSpace#10080 for more details
• Updates Docker build script & e2e tests to use ghcr.io (instead of using docker.io). This helps avoid DockerHub's aggressive rate limiting (see DockerHub is throttling all DSpace image builds causing relatively frequent Docker build failures in GitHub Actions DSpace#10092

Instructions for Reviewers

• The changes in this PR will all be tested in the automated build/test process. Therefore, if this passes all automated tests, it can be merged safely.

[tdonohue]

Merging as this passes all automated tests. Verified that this results in e2e tests using the images from ghcr.io instead of those from docker.io.

This will need to be ported (either automatically or manually) to 8.x and 7.x
