aceeptance: add script to build and push the acceptance image

Previously, README.md contained instructions to build the acceptance
image, but they were outdated.

This commit adds a script that can be used to build and push the
acceptance image and adds the process instructions to README.md.

Additionally, updated the script that builds and pushes the GSS images.

 ## Updating the `acceptance` image
 
 - (One-time setup) Depending on how your Docker instance is configured, you may have to run `docker run --privileged --rm tonistiigi/binfmt --install all`. This will install `qemu` emulators on your system for platforms besides your native one.
