CI for testing GO compat 1.22.x failed to catch compat issue

During the 2.21.x release we encountered an incompatibility with f40 due to ignition requiring go 1.23 or higher even though ignition has CI which explicitly tests this.

You can see the failure here:

Start by reviewing the CI configuration for Go 1.22 compatibility testing and the vendored dependency metadata shown in the build log. Reproduce the Fedora 40 build with Go 1.22.12; done means CI reliably catches dependencies requiring Go 1.23 or newer.
