revert config changes made for a deploy if the deploy fails

### Description

In the dev and prod deploy scripts, configs are set before running the deploy. This means that the config values in Azure are updated even if the deploy fails.

### Possible Fix

Exploration for fixing this...

* confirm whether configs are or aren't reverted if the deploy fails
* if not reverted, save configs in the action workflow before updating them
* if the deploy fails, revert the configs in the action workflow
