Add a SecureVersion instance

What does this MR do and why?

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

It is envisaged that this will be kicked off by the pipeline at gitlab-org/quality/ci/secure-testing/version-matrix!1 (merged)

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.

An EE license is required, as this targets Secure functionality.

A project URL and project name for import are needed. See test step below.

What this does:

• Spins up an instance of given version
• Disables security modal (for older versions)
• Sets license
• Sets up a runner
• Imports a project
• Checks that the project pipeline has been successful, if so this job passes

It works outside of the GitLab E2E RSpec framework.

How to set up and validate locally

NOTE: If your license was created for testing, use the GITLAB_LICENSE_MODE variable:

GITLAB_LICENSE_MODE=test EE_LICENSE=$(cat ~/path/to/gitlab-team-member-license) PROJECT_URL='https://gitlab.com/gitlab-org/quality/ci/secure-testing/secure-matrix-test.git' PROJECT_NAME='secure-matrix-test' ./exe/gitlab-qa Test::Instance::SecureVersion gitlab/gitlab-ee:16.5.0-ee.0

In particular note that the token (on runner create) and License values are masked.
