Communication: Invalid Markdown for Lists in Artemis

[JanaNF]

Description
It seems that Artemis currently adds the bullet point (•) directly as a text character instead of generating valid Markdown syntax for lists. This leads to issues where the following output is produced:

• Item 1  
• Item 2 

Instead of the proper Markdown format:

- Item 1  
- Item 2  

Artemis/src/main/webapp/app/shared/monaco-editor/model/actions/bulleted-list.action.ts

Line 4 in 83ac531

const BULLET_PREFIX = '• ';

Expected Behavior
Lists in Artemis should be generated using valid Markdown syntax to ensure compatibility and proper rendering across all platforms

Actual Behavior
Artemis produces lists with the bullet point (•) embedded as plain text. This approach causes:

• Compatibility issues, particularly on iOS and Android.
• General rendering problems in Markdown-compliant tools.

Steps to Reproduce

1. Create a list in Artemis.
2. Observe the output format in the preview or exported text.
3. Notice the use of the • character instead of Markdown-compatible list syntax.
4. In the iOS app you can see that it did not got formatted (see screenshot)

Environment
Artemis Version: 7.7.2
Platforms: Safari

Additional Notes
This issue likely affects all platforms (web, iOS, Android) and could lead to inconsistent behavior. As Markdown is widely used for formatting, generating invalid syntax should be avoided.
