Investigate Input.IgnoreObjectSource bug

[BernieWhite]

Description of the issue

The option Input.IgnoreObjectSource is not working correcting with the following options:

input:
  # By default, objects read from file using inputPath will be skipped if the file path has been ignored.
  # When set to true, additionally objects with a source path that has been ignored will be skipped.
  ignoreObjectSource: true
  
  # By default, PSRule will process all files within an input path.
  ignoreUnchangedPath: true

  pathIgnore:
    # Ignore other files in the repository.
    - '**'

    # Include deployment files.
    - '!deployments/**/*.bicepparam'
    - '!deployments/**/main.bicep'

Expected behaviour

All files should be ignored except *.bicepparam and main.bicep files.

Module in use and version:

• Module: PSRule
• Version: 2.9.0
