[m-rev.] diff: disable .NET backend by default

[Julien Fischer]

Estimated hours taken: 0.1
Branches: main, release

Disable the .NET backend by default.  This is to prevent the installation
process breaking on Linux systems that have either DotGNU or Mono installed.

configure.in:
	Disable the .NET backend by default.

README.DotNET:
	Mention that configure must be invoked with `--enable-dotnet-grades'
	option in order to enable .NET support.
