fix: use TSiblingData for previousSiblingDoc in FieldHook (#14503)

### What?
In field hooks, `previousSiblingDoc` is typed as `TData`.

### Why?
This value should actually be typed as `TSiblingData`, I've confirmed
the sibling data is actually what is returned when a field hook runs.

### How?
Updated `FieldHook` typing, as well as `RichText` field hook typings

Fixes #9735
