✨ Get Ginkgo version in Makefile from go.mod

[oscr]

What this PR does / why we need it:

Exploring a way to avoid having to hardcode dependency versions in the Makefile that already exist in go.mod.

This would allow having dependabot bump these dependencies automatically to get a) notification of new versions b) knowledge of breakage asap.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):

cc @sbueringer Semi related to the discussion about make. A wild idea to get the version from go.mod. Only works for the dependencies in the mod file. Mainly to allow dependabot to bump dependencies and find breakages automatically in new versions. I'm not sure if it's a good idea yet 😁

@oscr Somehow missed this PR entirely. GIven that we recently forgot to bump the ginkgo binary when we bumped the dependency...

I'm in favor of this PR as to me it's a good incremental improvement to guarantee versions are sync
