docs: Update orphan strategy config to reflect new defaults

In [v1.41](https://github.com/backstage/backstage/releases/tag/v1.41.0),
the catalog's `orphanStrategy` and `orphanProviderStrategy` were changed
to default to `delete`. This change updates the docs to reflect this.

+If you have had providers installed in the past that ingested entities into the catalog that you want to keep, the recommendation is to add the provider back to the catalog. If you don’t want the provider to run, you can schedule it with a very large interval.
