Enable additional regions on account creation

[diegoroccia]

Subject of the issue

Please excuse if the feature is documented and I could just not finf it.

I am looking into how to enable additional regions on account creation. It has to be on account creation because I am setting AWS SSO in that region, so not having the region enabled makes the pipeline fail because the org-formation is unable to assume the role in the target account

Specifically, I am using ap-east-1
