Safe Settings doesn't detect removed rules from repository rulesets

## Problem Description
When one or more rules are manually removed from a ruleset or when required status checks are modified, Safe Settings doesn't detect any changes. Interestingly, it does detect changes when rules are added, ruleset name is changed or bypass actors are modified.
### What is actually happening
The app doesn't recognise changes when rules are removed from a repository ruleset.
### What is the expected behavior
If someone manually removes the rules the app should revert those changes and add the rules back in.
### Error output, if available
