[Bug]: Critical! Default image config is not usable.

[JerryNixon]

Expected

Pull 2.0.1-RC and set DAB_CONNSTRING environment variable and auto-config takes over and works.

{
  "$schema": "https://github.com/Azure/data-api-builder/releases/download/2.0.1-RC/dab.draft.schema.json",
  "data-source": {
    "database-type": "mssql",
    "connection-string": "@env('DAB_CONNSTRING')"
  },
  "runtime": {
    "rest": { "request-body-strict": false },
    "host": {
      "mode": "development",
      "authentication": { "provider": "Unauthenticated" },
      "cors": { "origins": ["*"], "allow-credentials": false }
    }
  },
  "autoentities": {
    "default": {
      "patterns": {
        "include": ["%.%"],
        "name": "{schema}_{object}"
      },
      "permissions": [{ "role": "anonymous", "actions": ["*"] }]
    }
  }
}

Actual

Existing default schema has things (like entities) that make it unusable.

1. Should default database-type to mssql.
2. connection-string should be ""
3. data-source.options should be omited.
4. request-body-strict should be false
5. authentication.provider should be anonymous
6. cors.origins should be *
7. entities should be omitted (this is the root of the failure)
8. autoentities should be %.% (this is the other root of the error)
