We avoid resetting the internal FFmpeg decoder on framerate changes, but in turn this means we were not updating the framerate on the srcpad, which was clearly incorrect. This change keeps the optimization but ensures that we renegotiate downstream when framerate changes occur. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8118>
