Bug description

Currently Nextcloud lacks the mimetype definition of tab-separated-values(TSV) files as in: https://www.iana.org/assignments/media-types/text/tab-separated-values and will trigger a browser download instead of opening such file in Richdocuments.

While the file association is missing the Richdocuments app, I found that Nextcloud doesn't recognize such documents as well so it should also be fixed.

Steps to reproduce

Search for TSV in https://github.com/nextcloud/server/blob/master/resources/config/mimetypemapping.dist.json

Expected behavior

TSV file type definition available in https://github.com/nextcloud/server/blob/master/resources/config/mimetypemapping.dist.json.
