Reinstate Community EE Bring Your Own License AMI

With the completion of the recently published AWS marketplace listing in 11.11, we have replaced our existing EE AMI, which was unlicensed, with an EE AMI that has an Ultimate license included in order to create a marketplace listing and facilitate private offers.

There are customers, however, that are utilizing the unlicensed EE AMI via automation to run GitLab on AWS and applying their own license via a BYOL model.

We should reinstate an unlicensed EE AMI in the AMI listings so existing customers can utilize their existing workflows for GitLab upgrades.
