    session-rdp: Default to max 60 FPS, when using graphics pipeline
    
    With the graphics pipeline, gnome-remote-desktop has a way to control
    to control the encoding rate based on the speed of decoding and
    displaying frames on the client side.
    With the PipeWire stream running at 60 FPS also decreases the frame
    latency between when the frame was rendered by mutter and when
    gnome-remote-desktop can start encoding it.
    A 60 FPS PipeWire stream does not mean that 60 are always reached.
    The maximum FPS is determined by the minimum of the encoding rate in
    gnome-remote-desktop and the frame acknowledge rate of the RDP client.
