instantiating the templates doesn't do anything about fable-templates

dotnet/templating#1401
Looks like it's a bug in dotnet.exe and the fix should ship with the .NET Core 2.1.0 full release.

It seems that specifying F# as the language makes it work:

dotnet new fable -lang F#
dotnet new fable-electron -lang F#

Both of the above work.

Maybe F# is not set as the default for the template? I notice in the list below:

That all of other templates which specify a language mark the default language with [], but the fable templates do not mark F# with this (even though it is the only language). It seems a little silly they wouldn't have the tool pick the only language automatically as the default though, even if it wasn't marked as such :^)

Thanks for the report! Yes, it was a regression in one of the dotnet SDK releases, which is a bit annoying. I hope they fix it quickly :)
