fixes #11719 - mysql2 dep must match ActiveRecord's runtime dep
When AR loads the mysql2 adapter, it calls 'gem' with a version spec. For our bundle to include a compatible version of mysql2 and not the latest version, the spec needs to match AR's.
(cherry picked from commit 47604a20219bdf0f6c72fde9dabd3f47f0513364)
