Feature request: Configuring snapshot store on Azure

[KMKalkmanCRX]

Is your feature request related to a problem? Please describe.
Followup on #7503
We would like to be able to configure the container for the snaphot store on azure more, specifically:

• Allow storing the snapshot store in a subfolder of a container
• Configure the container to be public or otherwise

Describe the solution you'd like
In the custom HOCON

https://github.com/petabridge/Akka.Persistence.Azure?tab=readme-ov-file#custom-mode-hocon
I would like it to work to include a / or \ in the container-name field to denote storing in a subfolder, or to add an extra field to denote the path within the container (if empty store in root).

I would also like a separate field to denote whether the container is public or not.

Describe alternatives you've considered
Some other way to change these configurations would be fine by me, via the setup class or some such thing https://github.com/petabridge/Akka.Persistence.Azure?tab=readme-ov-file#using-configurable-setup-class-with-akkahosting
