Add end to end tests for pull requests from develop to main more thorough pre-release testing

[jpower432]

Issue description / feature objectives

Adding end to end tests for common trestle use cases can catch early bugs and regressions increasing release quality. Suggesting this be added as a validation step to release pull requests.

Caveats / Assumptions

• This could be added to all pull requests, but may slow execution. Unit testing here might be enough.

Completion Criteria

• Identify critical workflow test cases to include
• Any generated OSCAL documents should be validated against the relevant JSON schema for the currently supported version of OSCAL
• Check validity with the oscal-cli
