Derive dev-tool CLI versions from go.mod (ginkgo, protoc-gen-go, goimports) (#10024)

* Derive Ginkgo CLI version from go.mod in test/Makefile

Hardcoded @v2.22.0 pin drifted from go.mod's v2.28.3, causing
Ginkgo CLI/package version mismatch warnings.

Fixes #10023

* Derive protoc-gen-go and goimports versions from go.mod in build-image

Same drift issue as #10023: Dockerfile hardcoded @v1.33.0 and @v0.33.0
while go.mod had moved on. Build context is hack/build-image, which
doesn't include go.mod, so versions are computed in the Makefile (which
does have go.mod) and passed through as build-args, same as GOPROXY.

protoc-gen-go-grpc and controller-gen/setup-envtest/golangci-lint are
left as-is: no matching go.mod entry, or independently versioned from
the module they live alongside.

Fixes #10023
