[Enhancement]: Add Support for Emulator for Azure App Configuration

Problem

I am the maintainer of an emulator for Azure App Configuration and I have received feedback from users that they would value a Testcontainer module to allow them to more easily test their applications.

Solution

I would like to contribute a module for the emulator and was wondering if this should be done in this repository and published as Testcontainers.AzureAppConfiguration or similar or hosted in the emulator's repository.

Benefit

The benefits of having a module for the emulator include being able to more quickly and easily enable integration tests of applications that are dependent on Azure App Configuration.

Alternatives

I would be more than happy to alternatively maintain the aforementioned module in the emulator's repository and publish it as AzureAppConfigurationEmulator.Testcontainers or similar.

Would you like to help contributing this enhancement?

Yes

Start by resolving whether the Testcontainer module belongs in this repository or the emulator's repository, then determine the appropriate package name and ownership. Done means the hosting decision is settled and a concrete contribution path for Azure App Configuration emulator integration tests is defined.
