fix: 🐛 Add the temp directory created to the safe directory list

[JamesIves]

Description

Adds the temp workflow directory to the safe list of directories. A deployment failure can occur here depending on the type of files moved around by the workflow, and as such we need to mark this directory as safe too to prevent dubious ownership.

Testing Instructions

This has been validated on a test branch. I have also added a replicate PR in the integration test to validate root level deployments to ensure they continue to work. It doesn't repro this bug, but it's something at least.

Additional Notes

Closes #1694
