Add support for LibreOffice's default bibliography styles

[DTT12912]

Closes #13049

This PR adds support for LibreOffice's default bibliography styles in JabRef's LibreOffice integration. The changes include:

1. Added new bibliography styles:

   • "Bibliography Heading" for the bibliography section heading
   • "Bibliography 1" for bibliography entries (default)
   • "Text body" as an additional style option

2. Updated the UI:

   • Renamed "Modify bibliography title" dialog to "Modify bibliography properties"
   • Added a new dropdown to select bibliography body text format
   • Maintained backward compatibility with existing styles

3. Backend changes:

   • Added new styles to CSLFormatUtils.Format enum
   • Updated OpenOfficePreferences to store bibliography body format
   • Modified CSLCitationOOAdapter to use the selected body format

These changes ensure that JabRef uses LibreOffice's default bibliography styles by default while still allowing users to choose alternative styles if desired.

Did you read the issue properly? Did you understand the difference between formatting of the bibliography header and the bibliography text?

[subhramit]

The PR is blindly copy-pasted (or AI-adapted) without manual testing, screenshots, proper preference settings, etc.
Tests are also failing.
Please go through the existing code again, try to understand it, make changes, test and mark ready for review once done.
Ask questions if you encounter any.
If the PR is at a ready for review state without proper understanding, I will be closing it (and you can work on simpler issues).

Also do not mark the mandatory checks blindly. We expect sincerity from contributors - read what you are marking as "done".

Hi @subhramit Thank you for looking into the PR. I totally understand your frustration. Right now I'm just trying to figure out about the project . I will ping you if I have any questions or once I take the PR out of draft

Since you are probably a beginner, here are some more hints about the things that are missing:

1. The root preference declaration and default setting should go into JabRefCliPreferences (you can find the corresponding code in the linked PR in the issue).
2. The paragraph formatting for the title of the bibliography and the body will be separate. To understand this, try out the libreoffice integration. You can check out this as well as this. This will also help you test your changes.
