fix(shortyservlet) remove noise in logs #30709 (#30768)

### Proposed Changes
* Added a `try-catch` block to handle `DotDataException` when fetching
the `Contentlet` in `ShortyServlet`.
* Removed the unused `getImageContentlet` method to reduce redundancy.
* Updated logging to reduce verbosity when an image does not exist,
replacing it with a concise debug log.

### Checklist
- [x] Tests
- [x] Translations
- [x] Security Implications Contemplated (add notes if applicable)

### Additional Info
The changes address a NullPointerException occurring when a requested
image by shorty does not exist. This was causing excessive error
logging, making it difficult to identify the actual issue. By catching
`DotDataException` and logging a debug message, we now ensure that logs
remain clean and the system handles missing images gracefully.
The removed method `getImageContentlet` was no longer necessary as its
functionality was integrated directly into the updated code.
