Create or update custom property values for organization repositories

Create new or update existing custom property values for repositories in a batch that belong to an organization. Each target repository will have its custom property values updated to match the values provided in the request.

A maximum of 30 repositories can be updated in a single request.

Using a value of null for a custom property will remove or 'unset' the property value from the repository.

To use this endpoint, the authenticated user must be one of:

• An administrator for the organization.
• A user, or a user on a team, with the fine-grained permission of custom_properties_org_values_editor in the organization.
