Provide a more automated cleanup for Kratix installs

[abangser]

To clean up/remove an install of Kratix we suggest following the docs here.

While this is accurate, it is not intuitive as it requires deletions in a specific order. Specifically, if Kratix is deleted before the WorkPlacement resources, there may not be a clean up completed in the StateStore as the reconciliation loop to make that change will not ever run.

Ideally this process would be less likely to be overlooked by making Kratix smart enough not to remove its ability to clean up its parts. This may not be possible with a pure Kubernetes solution, but we should investigate that first and look for scripted solutions as a second option.
