Describe the solution you'd like

Currently, ASP.NET Core supports configuration providers for JSON, XML, and INI files. However, YAML is a popular configuration format due to its readability and support for complex data structures. Adding a YAML configuration provider would enhance the flexibility and usability of ASP.NET Core applications, especially for developers who prefer or require YAML for their configuration needs.

Benefits:

• Increased flexibility in configuration file formats.
• Improved readability and maintainability of configuration files for developers who prefer YAML.
• Enhanced support for complex configuration scenarios.

Additional context

YAML is widely used in various applications and tools, such as Kubernetes and Ansible, making it a valuable addition to the ASP.NET Core configuration system. By supporting YAML, ASP.NET Core can better align with the preferences and needs of a broader developer community.

Looks like this issue should be transferred to dotnet/runtime as that is where the majority of the configuration providers are implemented.
