Clarify registry storage delete option behavior
If this is not set to true, users will get an error deleting a project through the web ui.
If users follow our documentation for setting up an alternate storage driver, then we overwrite this setting, and it gets set to false

We should probably do one of
- Update the documentation to state that it should be set to true
- Update the code to always set it to true unless it is explicitly set to false
