TypeScript definition for connected and disconnected seem wrong

[liayn]

The type definitions for $cable.connected and $cable.disconnected are wrong in the sense those properties do not seem to actually exist.
At least I couldn't find a word within the src folder.

actioncable-vue/types/vue.d.ts

Line 18 in ac1c863

connected: boolean;

I guess those two can be removed and it would save some working hours searching why "connected" is never true.
