Pull request overview

Fixes a regression in the PostgreSQL Flexible Server database create path where az postgresql db create (aka az postgres flexible-server db create) stopped honoring --charset/--collation due to sending an incorrect request payload shape to the service.

Changes:

• Update the database create request body to use the correct properties bag for charset/collation.
• Extend the flexible server DB scenario test to pass --charset/--collation and assert they are present in create/show output.
