[chore][CI/CD] Upgrade golang 1.22 version for unittest-matrix

[crobert-1]

Description:

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.

Link to tracking Issue:
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:

Looks like there are still failures intermittently, but much less impacting, and a different kind. The first failure was a unittest failure on an ARM run, the second was vmmeter failed to clean up properly. Since all tests still run, both of these are better in my mind than the current result of many tests being cancelled due to arm failures.
