As seen in #507 and #569, there is no guarantee for us that minor
dependency updates are actually minor updates for the dependent
application itself. The Chart version might be minor - and therefore
automatically merged when build is green - but the used Docker image
inside the Chart could still be a major version change.
To effectively prevent such automerge when the application major version
changes, there is now a test file that has the currently used major
versions hard-coded. In case of an actual major bump, this file has to
be adjusted.
Looking at `redis-cluster`, there might be several major Chart versions
with the same major application version.
This PR is related to #409 but does not fully resolve it.
