BAU - Correct github trigger conditions

[robk-dluhc]

Use the correct subset of app, config, db to trigger deployment.

Change description

The trigger had been cut-and-pasted, which didn't cover all the right subdirectories.

• [n/a] Unit tests and other appropriate tests added or updated
• [n/a] README and other documentation has been updated / added (if needed)
• Commit messages are meaningful and follow good commit message guidelines (e.g. "FS-XXXX: Add margin to nav items preventing overlapping of logo")
