Update install/installer go.mod for transitive dependency changes

The installer uses replace directives pointing to local component
directories. When those components' dependencies were updated (grpc,
protobuf, x/net, etc.), the installer's go.sum became stale, causing
the linter's type checker to fail to resolve packages — which surfaced
as cascading 'undefined' errors in CI.
