Support `dotnet new library` as an alias to classlib

[T-Gro]

Product

dotnet CLI (dotnet new)

Describe The Bug

I found it natural to create a new library project by saying its a library. As a human, when speaking about project types, we use terms like console/winforms/wpf project, but I would never say out loud "Yeah, that code lives in a classlib project".

When I tried dotnet new library on a fresh box, it yielded an error. I think library should be supported as an alias to classlib.

To Reproduce

dotnet new library -lang F#

No templates or subcommands found matching: 'library'.

Additional context

I tried to follow GH copilot's tips on finding the right repo, this was one of the few that was not a made up name. It is very possible my issue still belongs somewhere else alltogether.
