Draft: Add a NoVersionCheck instance

What does this MR do and why?

As per gitlab-org/quality/quality-engineering/team-tasks#3071

Addressing the failures at https://gitlab.com/gitlab-org/quality/ci/secure-testing/version-matrix/-/pipelines/1575616218 for gitlab-org/quality/ci/secure-testing/version-matrix!1

This adds an "instance" to allow the use of a specified image, but it also runs a rails command to disable the security version check modal on login.

Without it, if we spin up and test against an older instance image, this modal fails our specs on login (see screenshot)
