[Feature Request] Support fenced code block styles that compatible to learn.microsoft.com

[filzrev]

Is your feature request related to a problem? Please describe.

I want to use learn.microsoft.com style codeHeader for Fenced Code Block syntax.

Samples Image:

https://learn.microsoft.com/en-us/aspnet/core/fundamentals/minimal-apis/aspnetcore-openapi?view=aspnetcore-9.0&tabs=visual-studio#add-and-configure-openapi-document-generation

On above example. csharp fenced code block is rendered with "C#" header div region.

Describe the solution you'd like

Add custom CodeBlockRenderer implementation to support following features.

• If language is specified (e.g. csharp). Display normalize language name at codeHeader (e.g. C#).
• Change copy button location/style to learn.microsoft.com style.
• If language and filename is specified (e.g.: csharp Sample.cs). Display filename at codeHeader (e.g.: Sample.cs) instead of language name. (Some other markdown processor support this kind of features)

Additional context
trailing string after Fenced code block is defined as info string by CommonMark Spec.
Thought info string format is not standardized.
