Build container images on Github Actions and push to multiple registries (#26247)

Modifications:
- Modify the workflow to build container images without pushing when the workflow file itself is modified
- Strip the leading ghcr.io/spack/ from env.container env.versioned to prepare pushing to multiple registries
- Fixed CentOS 7 and Amazon Linux builds
- Login and push to Docker Hub as well as Github Action
- Add a badge to README.md with the status of docker images
