Remove old regex pattern from CensoredFormatter (pymedusa#6705)

* Remove old regex pattern from `CensoredFormatter`

Newznab used to be a long string, and didn't have actual config sections, but that's changed now.
So now when newznab/torznab providers and loaded, the API key gets added to the censored items list.

The other reason for removing this is because the pattern isn't very accurate and can cause issues with logs (noticed this with a log from `tornado`)

* Update changelog
