Fix the rake update_depedencies task to respec the bundler version #8395
We live in an unfortunate world of mixed bundler versions right now. Our gemfile.lock currently is 1.17 locked. What that means is even if bundler 2.x is used it should fall back to 1.17 and any bundle updates won't bump that locked version. This works fine on the CLI, but isn't honored programmatically in our rake task. This results in Expeditor bumping the gemfile.lock and any PR it opens to update dependencies must be closed.
