x/build: x/example 1.22 builders are failing

[timothy-king]

x/example/ragserver/{ragserver/go.mod,ragserver-langchaingo/go.mod,ragserver-genkit/go.mod} require 1.23. This requirement cannot be met on the 1.22 builders and is breaking them consistently. Example output.

 go: go.mod requires go >= 1.23.0 (running go 1.22.7; GOTOOLCHAIN=local)

We should either downgrade these to 1.22 [if 1.23 is not needed) or disable the 1.22 builders for this repo as they cannot given a signal.

This is a dup of #69332. Thanks @gabyhelp.
