[Schema Inaccuracy] company and email properties of team-organization (and likely organization-full) should have null as available

Schema Inaccuracy

team-organization does not specify that null is an acceptable value for company and email properties. Neither does organization-full yet my org has a null email and company.

Expected

The company and email properties can be null.

Reproduction Steps

$ curl -X POST https://api.github.com/orgs/DriscollsInc

company and email are null and, to be frank, I don't even know how I'd go about setting company on this Org at this point.

This also applies to the location field, which is also nullable but is specified to always be a string.

Also applies to name and blog fields.
