Renovate go mod bumps result in go get -d -t ./... failures

[thardeck]

We had at least two go mod bump prs by renovate where renovate itself realized that there was an issue but still created them.

rancher/fleet#2304

Command failed: go get -d -t ./...
go: github.com/imdario/mergo@v1.0.0: parsing go.mod:
	module declares its path as: dario.cat/mergo
	        but was required as: github.com/imdario/mergo

rancher/fleet#2305

Command failed: go get -d -t ./...
go: gopkg.in/go-playground/webhooks.v6@v6.3.0: parsing go.mod:
	module declares its path as: github.com/go-playground/webhooks/v6
	        but was required as: gopkg.in/go-playground/webhooks.v6

This is a very specific issue: a dependency changing its module name. IMO these cases are best handled manually.

Now the question is, should a PR be created for this or not? Given that this is configurable via prCreation, I think each team can use whatever option it works best for them. So to avoid noise from failing PRs a team can change their .github/renovate.json to contain: "prCreation": "status-success".

But by default, I think we should continue to open those PRs so at least teams know that there is a dependency to be updated and it contains breaking changes, however they will need to manually create a superseding PR for it.

@pjbgf just for the records I have another example:
