zarr media type should be application/vnd.zarr instead of application/vnd+zarr

ZARR = "application/vnd+zarr" # https://github.com/openMetadataInitiative/openMINDS_core/blob/v4/instances/data/contentTypes/zarr.jsonld

The current ZARR media type value does not conform to recommendations for media types. There are two issues:

1. Convention is application/vnd.{vendor-specific-part}, not just vnd
2. the +{other type} is only used when the media type is a more specific version of another media type, like +json, not when it's a "new" format itself.

Yeah here's a ref for zarr https://humanbrainproject.github.io/openMINDS/v3/core/v4/data/contentType.html

I also noticed that parquet has an official mediatype now and it's "application/vnd.apache.parquet" ref:https://www.iana.org/assignments/media-types/media-types.xhtml
