DOC - how do we import v2 namespaces and datapoints

[NicolasHug]

The way we write our docs largely influences what user/our code will look like.

Right now we mostly do

from torchvision.transforms import v2

v2.Resize()

There are different options like import torchvision.transforms.v2 as T

We also need to decide how to import the functionals (In the past we've been rather inconsistent and went for things like TF which is potentially confusing).

We also need to decide whether we import datapoints, datapoints as dp, or just import the objects directly from that namespace like from torchvision.datapoints import BoundingBoxes

This is more about user-facing docs / code than about our internal code, but ideally we would align that as well. Our refactored tests use transforms for the module and I find that annoyingly verbose for zero added clarity.

I don't think we'll come back to this, closing
