Remove provisioning for portal.bigcz.org

[rajadain]

Overview

The SSL certificates were removed in #3610, which broke deployments. By removing references to all infrastructure that depended on those SSL certificates, we allow deployments to resume.

Also updated the default.yml file in 1Password, with a CHANGELOG capturing the updates.

Other feature references to portal.bigcz.org will be removed in #3613.

Closes #3617
