Update the Functional and Smoke Tests to use the ScubaResults.json rather than the ProviderSettingsExport.json

[buidav]

💡 Summary

This is the follow up to PR #1316.
The current functional tests are heavily dependent on the ProviderSettingsExport.json with change to making
ScubaResults.json the default we need to update the functional tests to match the new behavior.

Smoke tests may need to be updated as well.

Motivation and context

To make sure our tests cover the final ScubaGear output: ScubaResults.json rather than the old ProviderSettingsExport.json.

Implementation notes

• Update the code in the Testing/Functional/Products to start using ScubaResults.json.
• Update the code in the Testing/Functional/SmokeTest to start using ScubaResults.json If necessary.
• Remove the -KeepIndividualJSON flags from Invoke-SCuBA and Invoke-SCuBACached in the workflow code.

Acceptance criteria

• Functional and Smoke tests work around the new ScubaResults output file.

Definitely requires some significant updates to our functional tests apparatus. Particularly for those working off cached data as methods like UpdateProviderExport and PublishProviderExport currently target the provider file for making changes.
