feat(react-scheduler): allow appointment resizing

[MaximKudriavtsev]

BREAKING CHANGE:

The Appointment component of the Appointments plugin has not received a style property. These styles have passed to the Container component of the Appointments plugin.

Before

...
<Appointments
  appointmentComponent={({ style, children, data, onClick?, onDoubleClick? }) => ... }
  ...
/>
...

After

...
<Appointments
  appointmentComponent={({ children, data, onClick?, onDoubleClick? }) => ... }
  containerComponent={({ style, children }) => ... }
  ...
/>
...
