DEPS: fix build when cache clear

[tbg]

This broke silently in #138283. As of that PR,

$ ./dev cache --down; ./dev cache --clear; bazel clean --expunge; ./dev build short

fail with

ERROR: no such package '@@org_golang_google_genproto_googleapis//rpc/code': The repository '@@org_golang_google_genproto_googleapis' could not be resolved: Repository '@@org_golang_google_genproto_googleapis' is not defined
ERROR: /private/var/tmp/_bazel_tbg/b1346cddcc70d57afdaa90f7f09f9b2c/external/com_github_buchgr_bazel_remote/server/BUILD.bazel:3:11: no such package '@@org_golang_google_genproto_googleapis//rpc/code': The repository '@@org_golang_google_genproto_googleapis' could not be resolved: Repository '@@org_golang_google_genproto_googleapis' is not defined and referenced by '@@com_github_buchgr_bazel_remote//server:go_default_library'
ERROR: Analysis of target '@@com_github_buchgr_bazel_remote//:bazel-remote' failed; build aborted: Analysis failed

Now it works.

Closes #139038.
