Update list of available Wasabi Regions

[UpcraftLP]

Is your feature request related to a problem? Please describe.
Wasabi has several more regions than what is currently available in the Region enum. (see the relevant Wasabi Knowledge Base article)

Describe the solution you'd like
Add the remaining regions to the list.

Describe alternatives you've considered
As a workaround I can currently just define a custom region, but supporting all of them out of the box would be appreciated.
