Revert to JSON schema draft-04 to address RapidJSON validator issues

[clovis517]

Schema changes to enforce constraints which were being bypassed due to dependencies on unsupported JSON Schema draft-07 functionality.

Unsupported functionality replaced :

   const
   if .. then
   exclusiveMinimum

@shaselton do we know if/when we can expect this to be approved?

FYI ... I just re-patched the TOC schema in my pull request, my first attempt was not enforcing the plan_sponsor_name requirement as intended.

Example files to test with :
This should FAIL: ... "Message: Object is missing the following members required by the schema: 'plan_sponsor_name'."
/schema-repo/examples/table-of-contents/INVALID.table-of-contents-sample.ein.MISSING_plan_sponsor_name.json

The in-network-allowed schema had the same plan_sponsor_name constraint issue. Fixed that (on my second try - ugh!) in the latest commit.
The issue this fixes : The following in-network file currently passes but should FAIL due to missing plan_sponsor_name :
