Do we not need the old hook too for backwards compatibility?

[lrafeei]

The location of these hooks did not actually move from previous versions. In the case of Redis and Docarray, there is an init.py file that imports these classes, so I'm just moving our hook for these vectorstores to be on the same level as the others.
