README in version 4.4.0

[bernardnormier]

A few issues with the latest README:

• it would be helpful to mention where the settings file is (.vscode/settings.json)
• "Each configuration..." and its sublist should not be on the same level
• IceRPC is not spelled according to our branding guidelines
• addWellKnownTypes:
  • we need to document the default value
  • the WellKnownTypes are Slice well-known types and are RPC independent
  • but in practice "addWellKnownTypes" is about the Slice well-known types and many additional Slice types of lesser importance like IceRpc::ServiceAddress and IceRpc::StatusCode.
  • nevertheless the link goes to the WellKnownTypes folder

Maybe we should provide two variables:

• addWellKnownTypes (or includeWellKnownTypes?) for the Slice well-known types
• addIceRpcTypes/Definitions (or include...) for the IceRPC types/definitions

See:
https://nuget.info/packages/ZeroC.Slice/0.2.1 ( = Slice well-known types)
https://nuget.info/packages/IceRpc/0.2.1 (= IceRPC Slice files)
https://nuget.info/packages/IceRpc.Slice/0.2.1 (= additional Slice files provided by the IceRPC + Slice integration)
