Subject: [PATCH] Update Initial-Detection.md (#8053)

* Update Initial-Detection.md

While trying to add support for awplus under https://github.com/librenms/librenms/pull/7670, I was advised to delete the os_defs.cache file.

This was hugely helpful, as I wasted a number of hours trying to figure out why I couldn't get any changes to the OS configs to work.

* Small updates
