Improve data provider types

[andrico1234]

Only 3 param types required this

UpdateParams
UpdateManyParams
CreateParams

This small change allows us to pass through our data's types if we know what they'll be at this point, and defaulting to any if no type is passed through. The current types treat the data object as any.

As for naming, I'm not too keen on giving single letter names to the generic's arguments. I'll be happy to change T to Data or whatever you feel is most appropriate

FYI I had trouble linking RA using the instructions in the .README so I wasn't able to test the types in my own repo. AFAIK there aren't any uses of the dataProvider's update, updateMany, and create methods in any of the test repos.

I might have completely missed it though!
