automatically synced data from hasadna to odata should contain appropriate description

following this tweet: https://twitter.com/Yogevsha/status/1326027781378027520

regarding this package: https://www.odata.org.il/dataset/c08b9c48-9dfe-4327-a6d7-ac8305b923ec

we should provide a description to all the packages synced to odata describing their source (some details could be derived from the source, some might need to be added to the source to make it clearer)

Start with the linked OData package and the referenced tweet, then trace how data is synced from Hasadna to OData. Determine which source details can provide descriptions and which must be added upstream. Done means every synced package has an appropriate description identifying its source.
