Actions & PR Template verbessern (#223)

### Zugehörige Issue(s)

Closes #222

### Beschreibung

Die Push & PR-Pipelines wurden um Überprüfungen und Formatierung für die Lokalisierung erweitert. Außerdem wurde eine PR-Checkliste zum PR-Template hinzugefügt.

### Änderungen

- Template um `PR-Checklist` ergänzt (siehe Diff, gerne Ideen für mehr Punkte)
- PR-Pipeline überprüft jetzt ob `untranslated_messages.json` leer (also `{}`) ist. Wenn nicht, schlägt sie fehl
- In der Push-Pipeline werden jetzt die `.arb`-Files sortiert
- In der Push-Pipeline werden jetzt die lokalisierungen generiert
- Renovate Workflow hinzugefügt, welcher jede Woche die Dependencies überprüft (siehe [diese Test-PR](#244))

### Zusätzliche Anmerkungen

Ich wollt eigentlich auch einen Job zum generieren der DB-Files einbauen. Das hat jedoch nicht geklappt (siehe [hier](https://git.yannick-weigert.de/liquid-development/game-tracker/actions/runs/1013/jobs/3) oder [hier](https://git.yannick-weigert.de/liquid-development/game-tracker/actions/runs/1014/jobs/3)), weil der jedes mal mehr als 10 Minuten gedauert hat und dann getimeoutet ist
