[PieFed] Improper capitalization community links don't work

**Describe the bug**
Links to Communities with CamelCase names don't work in lowercase when using Voyager with PieFed and vice versa.

Lowercase community name:
https://lemmy.world/c/tipofmytongue@lemmy.world

!tipofmytongue@lemmy.world works ✅

!TipOfMyTongue@lemmy.world doesn't work ❌

CamelCase community name: https://lemmy.world/c/AlbumArtworkHeaven

!AlbumArtworkHeaven@lemmy.world works ✅

!Albumartworkheaven@lemmy.world doesn't work ❌

**To Reproduce**
Steps to reproduce the behavior:

1. Go to [this comment](https://lemmy.world/comment/21190592) or [this comment](https://lemmy.ca/comment/20764067) with a PieFed account on Voyager
2. Click on the community links
4. See error 'Nothing to see here'

**Expected behavior**
Handle capitalization in community links like Lemmy on Voyager. It just works, regardless of CamelCase, lowercase or other.
