Detect go.mod required updates dynamically

[shajmakh]

Create a GH workflow that would verify if go.mod requires updates (make deps-updates returns git differences).
Possible challenge is to maintain same go version on all supported branches as is now (toolchain is fine to be bumped) .
This is to match deps minimum required Go version.

I for one I welcome more automation and refinements, thanks for filing this issue! However I wonder what's exactly the goal here. Changing go version inside a release branch is exceptional and should be generally avoided. Are we trying to detect involuntary changes?

The goal of implementing this automation is to detect situations in which the bumped dependencies require go version that is greater than the one specified in go.mod. If Go version that is specified in go.mod matches the minimum required for all the deps, the check will pass. otherwise it will fail warning about invalid deps bump.
