Pattern: Unpinned version in gem install

Issue: -

Description

Version pinning forces the build to retrieve a particular version regardless of what’s in the cache. This technique can also reduce failures due to unanticipated changes in required packages.

Example of incorrect code:

FROM ruby:2
RUN gem install bundler

Example of correct code:

FROM ruby:2
RUN gem install bundler:1.1
