fix: avoid installing the registry multiple times

While the fill-test-ci-values target's dependency on install-registry
was correctly manipulated by the SKIP_INSTALL_REGISTRY variable, the
install-lagoon-build-deploy target had a hard-coded dependency on
install-registry. The result was that the registry would get installed
multiple times anyway via the fill-test-ci-values target via an indirect
dependency.

Fix that by removing the dependency that install-lagoon-build-deploy has
on install-registry when SKIP_INSTALL_REGISTRY=true.
