fix(build): restore correct tool versions in Makefile

The sed command incorrectly replaced all VERSION ?= lines.
Restore correct versions:
- OPERATOR_SDK_VERSION: v1.39.2
- KUSTOMIZE_VERSION: v5.4.3
- CONTROLLER_TOOLS_VERSION: v0.17.2
- ENVTEST_VERSION: release-0.19
- GOLANGCI_LINT_VERSION: v2.1.5
