API collections/{collection}/override/v1 postCollectionsCollectionOverrideV1["body"] defined incorrectly

[dmshvetsov]

To nullify value with collections/{collection}/override/v1 API endpoint, for example discordUrl field, a caller must pass null value but postCollectionsCollectionOverrideV1["body"] type does not allow null for collections model fields. In fact I was unable to use empty string "" to "nullify" discordUrl with the override/v1 endpoint, that make me think that postCollectionsCollectionOverrideV1 type defined incorrectly.

Can you help me understand if I'm right or if I'm doing something wrong, or if the type or documentation needs to be corrected. Thank you.
