feat(ci): Print Go version from Makefile.var when starting a pipeline
@jnycz This MR prints the current Go version at the start of every CI pipeline, in this repository.
This should make situations like this one easier to debug, when the problem is related to our "official" Go version:

Don't merge before S36 milestone.
