Fix build issues with missing rules_docker loader binary (#2300)

Summary: Fix build issues with missing `rules_docker` loader binary

The `rules_docker` repository moved its image pulling binaries from
storage.googleapis.com to mirror.bazel.build. Last week, the
storage.googleapis.com binaries were removed causing existing builds to
break. This upgrades `rules_docker` to a version that includes the [new
URLs](bazelbuild/rules_docker#2291 (comment))
for the loader binaries.

Relevant Issues: N/A

Type of change: /kind bugfix

Test Plan: Build succeeds
