set up dap for c# and switch dap-python from using debugpy-adapter in path

Mason installs these DAP adapters so that they appear to be in path for
any process spawned by nvim, so I can just use that instead. Seems to be
working perfectly. NOTE: to debug a c# application the root folder of
the current vim session should contain the .csproj file you want to
debug.
