[Bug]: Storing Granules to ES is not storing bounding box from STAC.

[wphyojpl]

Currently,

• Cumulus metadata is transformed into STAC manually.
• It doesn't have bounding box which is hardcoded as "entire world".
• It is already reading STAC metadata file (if any) for custom metadata: stac_input_meta = StacInputMetadata(json.loads(self.__read_pds_metadata_file(each_potential_file)))
• It can read bounding box info and geometry info from there instead of hardcoding them.
