Trigger warning for PRs likely requiring updates to management-plane-charts

[c-pius]

Description

Find a way that notifies us when PRs to lifecycle-manager are likely requiring changes to management-plane-charts. For instance, changes to the configuration or the E2E test files (we used to have a github action that was comparing the make manifests" outcome between main head and PR). If there are changes, it is likely that we also need to modify something in management-plane-charts and the developer should double check.

Document what is expected from the assignee in case the above is triggered. E.g., extend the AC of the original issue to account for the changes in management-plane-charts, create a PR that is preparing and testing the required change and can serve as a base for the release manager to create the new release.

Reasons

Prevent delayed releases due to the release manager finding out too late that changes to the charts are needed.
