[BUG]: Extra line in fenced code block in view mode

[alexandrescieux]

Describe the bug

Summary

In Jotty, when reading a note in view mode, fenced code blocks render with an extra empty line at the end.

This extra line is also numbered, so it looks like the code block contains one more line than it actually does.

View note :

Steps to reproduce

1. Create or open a note containing a fenced code block in the Markdown Editor.
2. Use this markdown fenced code block in any note :

```bash
Extraline with carriage return
```

3. Switch to view mode.

Expected behavior

The code block should display only the actual lines of code, with matching line numbers and no extra empty line at the end.

How do you run Jotty?

Docker

Jotty Version

It's also worth noting that the word and character counters are not counting words and characters in fenced code blocks.
