Contributes to #643

This pull request introduces support for integrating Adminer with SQL Server resources in the CommunityToolkit.Aspire.Hosting.SqlServer.Extensions package. The changes include adding a new WithAdminer method, updating documentation, and implementing comprehensive tests to validate the functionality.

New Feature: Adminer Integration

• Added a WithAdminer extension method to SqlServerBuilderExtensions to enable Adminer as an administration and development platform for SQL Server resources. This includes configuring Adminer containers and managing environment variables for SQL Server instances. [1] [2]
• Updated the SqlServer.Extensions project to include a reference to the Adminer project and link the AdminerLoginServer shared file.

Documentation Updates

• Updated the README.md file in SqlServer.Extensions to include instructions and examples for using Adminer alongside SQL Server resources. [1] [2]

Testing Enhancements

• Added multiple tests in ResourceCreationTests.cs to verify the functionality of the WithAdminer method, including tests for environment variable annotations, container image tags, and multiple SQL Server resources.
• Extended tests in AddAdminerTests.cs to validate Adminer integration with multiple database types. [1] [2] [3]

Example Updates

• Updated example applications (Adminer.AppHost and SqlServer.Extensions.AppHost) to demonstrate the use of the WithAdminer method for SQL Server resources. [1] [2]

Minor Enhancements

• Added System.Text.Json references in relevant files for handling JSON serialization of Adminer server configurations. (F56fd49aL11R11, tests/CommunityToolkit.Aspire.Hosting.SqlServer.Extensions.Tests/ResourceCreationTests.csR2)
