[chore][CI/CD] Upgrade golang 1.22 version for unittest-matrix (#32288)

Version 1.22.0 of golang only has a darwin OS build of arm architecture
available from `actions/setup-go` and `actions/go-versions`, so
hopefully upgrading to use 1.22.2 will help tests pass.

Fixes #32286

**Testing:** 
None yet, but hopefully from this CI/CD run of
`build-and-test/unittest-matrix` we can confirm if the updated go
version resolves this issue for arm testing.

Run shows `1.22.2` got picked up successfully:
