The checks fail because they run on webplatformtests/wpt.fyi:latest instead of webplatformtests/wpt.fyi:past-upgrade-modules. Every test passes locally.

That is correct. However, in the Go 1.21 update PR, the check also uses webplatformtests/wpt.fyi:latest but the CI passes. How did that pass?

Also confirm that I can see the docker image built in this branch

Because that PR didn't change the go.mod version format and Go 1.20 was still able to parse it. Essentially PRs that touch Dockerfile may or may not pass, depending on how backwards-compatible these changes are.
