Bug description

The link to "Learn more" in sealed sender settings points to https://signal.org/blog/secret-sender - probably instead of https://signal.org/blog/sealed-sender/.

Steps to reproduce

• Open settings -> privacy
• Tap "Learn more" in "Sealed Sender"

Actual result: 404 error in browser
Expected result: Show blog post https://signal.org/blog/sealed-sender/ - or whatever is intended.

Device info

Device: Motorola Moto G5
Android version: 8.1.0
Signal version: 4.30.1

Minor non-user-visible leftover variable name within signal4android == https://github.com/signalapp/Signal-Android/blob/master/src/org/thoughtcrime/securesms/database/helpers/SQLCipherOpenHelper.java#L288

signal4android strings.xml uses 'sealed sender' correctly (but signal4ios uses 'secret sender')

At least one icon in signal4desktop has metadata using 'secret sender' , https://github.com/signalapp/Signal-Desktop/search?q=%22secret+sender%22&type=Code , but otherwise no big problems (does not seem to link to blogpost url like the other clients).
