URI format doesn't work with newer ajv lib

[andorsk]

Expected: upgrade libs and all tests pass
Actual: Entity schema tests fails with URI format. AJV was anchored on the test suite at 6.12.5. Upgrade breaks the test.

Valid Entity Schema Test:
     Error: unknown format "uri" ignored in schema at path "#/definitions/image/properties/uri"

Recent AJV lib 8.12.0 does not permit uri as schema format, and test will fail.

-    "ajv": "^8.12.0",
+    "ajv": "^6.12.5",

Suggested fixes:

• Reformat format path as regex, so preformat rules aren't a problem.
• Possibly an issue with ajv implementation. Might have updated to need to use https://github.com/ajv-validator/ajv-formats
• Check if JSONSchema spec actually updated directly, such that it doesn't support uri format anymore.

just need to be explicit about which JSON Schema drafts work with v1 when we publish v1

[andorsk]

yea..the weird thing about this to be clear: It's the same schema. Just a different version of the lib processing this. 🤷

editorial changes in v1 (unless we get the actual fix in place)
actual fix in v2
