fix: respect storage options on create_index (#2460)

Currently, if `create_index` is used with non-standard storage backends,
or configuration options passed at runtime, `lance` does not respect the
storage option specified. This can be resolved by checking and passing
`storage_options` from the `create_index` methods to allow for the
`LanceDataset` to be recreated.
