fix(apps): fix unpackerr config storage (#16826)

**Description**
Fixes an issue where the Unpackerr chart would not automatically create
(or load) unpackerr.conf unless the directory (/config) was created and
mapped. The /downloads mapping was removed and replaced with /config
instead. The chart will start without the directory present, however, it
will only rely on environment variables.

⚒️ Fixes:  
- Maps /config so that the app can create and read unpackerr.conf
instead of relying on environment variables.
- Added whisparr to chart.yaml since it is supported by Unpackerr

- [ ] ⚙️ Feature/App addition

- [ ] ⚠️ Breaking change (fix or feature that would cause existing
