ci_runner_taggings_group_type table sharding

Column ci_runner_taggings_group_type.organization_id should meet all of the following requirements for Cell 1.0:

• has no default
• is not nullable
• has a foreign key to organizations

Once the above is done we can remove the table from 'ensures all organization_id columns are not nullable, have no default, and have a foreign key' in https://gitlab.com/gitlab-org/gitlab/-/blob/master/spec/lib/gitlab/database/sharding_key_spec.rb
