release-tools tag job fails due to bundle version error

Bundler::LockfileError: You must use Bundler 2 or greater with this lockfile.

https://sentry.gitlab.net/gitlab/release-tools/issues/2225523/?referrer=slack

This is an odd error to receive considering it was built with version 1.17.3: https://gitlab.com/gitlab-org/release-tools/-/blob/master/Gemfile.lock#L152

Example job failure: https://ops.gitlab.net/gitlab-org/release/tools/-/jobs/2242247

Utilize this issue to figure out what we need to do to rid of this error.

We recently upgraded to Bundler v2, which comes standard in Ruby v2.7.2, in gitlab-org/gitlab. You can either make release-tools:

1. Install bundler v2.1.4 via gem install bundler:2.1.4
2. Upgrade release-tools to use Ruby v2.7.2.

changed the description

gitlab-org/gitlab-build-images!335 (merged) updates the image to 2.7. Let me run the tests locally to see if they pass with 2.7.

Reopening, after merge and forcing a test run we are still failing: https://ops.gitlab.net/gitlab-org/release/tools/-/jobs/2242398

Odd, that we are installing the new version, but then the very next command performing a bundle install notes that it's NOT using the version we just installed
