Add Geo replication spec to pypi package test

What does this MR do?

This presents a new way to write Geo replication end-to-end tests that re-uses existing resource creation code without duplicating the code or separating code from the existing (non-Geo) test. We do this by

• adding a Geo replication example to the existing spec file ('it replicates to the Geo secondary site'), tagged with :geo
• adding a new rule to spec/runner.rb that adds ~geo rspec tag if there is no geo-secondary-address defined

Description of the test

• The existing pypi package spec generates a project, pipeline and publishs a pypi package in a before hook.
• The added Geo example navigates to the Geo secondary site and confirms that the pypi package has replicated.
• The test also deletes the project in an after hook

Testcase

Check-list

• Confirm the test has a testcase: tag linking to an existing test case in the test case project.
• Note if the test is intended to run in specific scenarios. If a scenario is new, add a link to the MR that adds the new scenario.
• Follow the end-to-end tests style guide and best practices.
• Use the appropriate RSpec metadata tag(s).
• Ensure that a created resource is removed after test execution.
• Verify the tags to ensure it runs on the desired test environments.
