Rename bbox -> bounds

[ashnair1]

'bbox' in kornia augmentations is used to identify bounding boxes of instances in an image. However, in GeoDatasets, bbox refers to the geographic bounds of the data. This PR aims to make these distinct by renaming 'bbox' in GeoDatasets to 'geo_bbox'

bounds could also be another option.

I would also be okay with removing it entirely. We currently don't use it anywhere. The original intent was that it could be used for stitching together prediction patches, but we don't do that yet. But I like bounds better than geo_bbox.

Looks fine to me, hoping you can convince at least one more person to review the name choice so we don't end up changing it again later. Note that rtree supports both bounds and bbox for the same objects, but they have different meanings. This has always confused me.

I think bounds is fine, another option could be extent

Looks like rtree's bbox is just an interleaved bounds. We could also consider query as another option.

Based on popular vote, I think we'll stick with bounds.
