  - Merge "fix loading of built-in inspection rules"
  - fix loading of built-in inspection rules

    The built-in inspection rules cannot be loaded because the jsonschema
    validates them against the expected API however the built-in rules had a
    'built-in' key that is not part of the schema and included the 'scope'
    key which was ultimately dropped before inspection rules support landed.
    The built-in rules also did not validate that the data was a list of
    rules before attempting to utilize it giving an incorrect error.
