Description

Is your feature request related to a problem? Please describe.
Zarr 3.x moved a number of types around and few other compatibility breaking changes. We currently try to support 2.x and 3.x in places like here but we should consider when to drop support for 2.x. This would help improve the typing of this module as well.

Research direction

Start with the compatibility logic in monai/inferers/merger.py around line 251 and inspect the other places that support both Zarr 2.x and 3.x. Clarify the target support policy and typing changes before determining which tests need updating; done means the project no longer maintains the Zarr 2.x compatibility paths.
