Enable $web and disable anonymous blob access on rpversions container

[tsatam]

Which issue this PR addresses:

Fixes ARO-14928

What this PR does / why we need it:

Updates our insertion of the deployed RP version into the rpversion storageaccount to use the static website hosting's $web container. This will allow us to disable anonymous blob access on the storage account generally, while still allowing access to content within the $web container.

This will require corresponding changes to our consumption of this content, as the URL will change from a .blob.core.windows.net URL to .web.core.windows.net.

Test plan for issue:

• Deploy this change in a non-production environment and ensure it:
  • Can be deployed over the existing configuration successfully
  • Enables static web hosting on the SA
  • Disables anonymous blob access on the SA
  • Inserts the version information successfully into the $web container
  • The version information within the $web container can be accessed anonymously.

The entire saveversion function could benefit from some dedicated unit tests, I will try to add these in a follow-up effort.

Is there any documentation that needs to be updated for this PR?

No

How do you know this will function as expected in production?

Above testing
