Update F# / C# official templates to dotnet 8

Dotnet 8 is the official dotnet release but the F# and C# templates are not on this.

What problem(s) would this feature solve?

This would allow everyone using these languages on Replit to get a modern, up-to-date environment.

Plus it prevents issues like someone trying to use a package but it DLs a version that is compatible with their dotnet (i.e. older) and then they get confused ab why the docs / code doesn’t align.

I have a Replit that updated F# to dotnet 8 and C# should be similar (sorry can’t link another thing cause new)

But problem is I can’t update official templates so need someone at Replit to do that
