Added

• Adds the ability to specify the key additional_checks, containing an array of additional checks to perform beyond those auto-discovered by the tool.
  See the documentation for further details.

Changed

• You can now specify individual jobs in the "checks" configuration as objects, instead of only as a JSON string. When specified in this way, the action will cast the job to a JSON string for you.

• The action now performs validations on each element of the "checks" configuration, raising warnings for anything malformed, and omitting those particular checks.
