ci: Get rid of Bundler's cache after installing gems [RUN ALL RSPEC]
requested to merge 327501-consider-getting-rid-of-bundler-s-cache-before-saving-the-gems-to-the-ci-cache into master
What does this MR do?
Thanks to a RailsConf talk, I discovered that Bundler is having its own cache under vendor/ruby/2.7.0/cache (when gems are installed under vendor as we do).
We probably don't need this Bundler cache as we refresh our own cache of gems every two hours.
From a quick check, it seems this cache accounts for 91MB: https://gitlab.com/gitlab-org/gitlab/-/jobs/1172621220#L65.
