Don't warn on implementation-specific notifications ()

Only warn when method name doesn't start with '$'. Per the spec:

  "if a server or client receives notifications or requests
  starting with ‘$/’ it is free to ignore them if they are unknown."

* eglot.el (eglot-handle-notification t t): Check method name for $.
