Update bundler from 2.4.6 to 2.4.22

What does this MR do?

Update bundler from 2.4.6 to 2.4.22

Sync the bundler version with gitlab-org/gitlab.

Changelog: changed

gitlab-org/gitlab bundler version: https://gitlab.com/gitlab-org/gitlab/-/blob/80bbcb8a2502a89175232b9fc99d08e7b04c1598/Gemfile.lock#L2101

Bundler installs the bundler version in Gemfile.lock anyway, but this way we end up installing two versions. This MR bumps the CNG bundler version so that the final images have only one bundler version installed.

Test Plan

> docker run -ti --rm registry.gitlab.com/gitlab-org/build/cng/gitlab-toolbox-ee:master gem list | grep bundler
