chore: use golang 1.N.P version syntax

[guydc]

What this PR does / why we need it:
CodeQL is reporting an invalid golang toolchain version syntax:

As of Go 1.21, toolchain versions must use the 1.N.P syntax.
1.22 in tools/src/setup-envtest/go.mod does not match this syntax and there is no additional toolchain directive, which may cause some go commands to fail.
CodeQL also found 9 other warnings like this. See the workflow log for details.

Thanks for spotting this, maybe that is the reason why I always receive toolchains not found for go1.22 error on my local dev env.
