Use `Bibliography Heading` and `Bibliography 1` styles for OO integration

[InAnYan]

Is your suggestion for improvement related to a problem? Please describe.

Currently, JabRef uses these styles in LibreOffice for "References" section:

• Heading of bibliography section: Heading -> Heading 2.
• Text in bibliography entries: Body Text

However, those are not the default styles for this section in LibreOffice.

Describe the solution you'd like

LibreOffice uses these styles for bibliography text:

• Heading of bibliography section: Heading -> Index Heading -> Bibliography Heading
• Text in bibliography entries: Index -> Bibliography 1.

Make JabRef use them.

Additional context

None.

Solution sketch (for CSL, as it is solved for JStyles):

1. For the heading format, add Bibliography Heading to the list (enum):
   

   jabref/jablib/src/main/java/org/jabref/logic/openoffice/oocsltext/CSLFormatUtils.java

   Lines 28 to 35 in 869e80e

   	public enum Format {
   	TITLE("Title"),
   	BODY_TEXT("Body Text"),
   	SUBTITLE("Subtitle"),
   	HEADING_1("Heading 1"),
   	HEADING_2("Heading 2"),
   	HEADING_3("Heading 3"),
   	HEADING_4("Heading 4");

2. For the text format, follow through how Allow user to choose CSL Bibliography title and format #12663 was solved (via Functionality to modify CSL bibliography title and format #12784). Just like that, we need to add an option to select the bibliography body text formatting. This roughly involves three steps - 1. adding backend logic (a similar enum, provision to use it, etc.), 2. Reflect that list in the UI (maybe add another button beside "Modify bibliography heading". Another, neater option could be extend the existing dialog to "Modify bibliography properties" instead of just the heading) 3. add preferences to store these.

@InAnYan Could you list how many text styles are there, apart from Bibliography 1? (or till Bibliography n, n=?)

[InAnYan]

No, only one Bibliography 1

[subhramit]

So I propose that three formatting options will be enough for the text - Text body (like default jstyles), Body Text (currently the hard-coded default) and Bibliography 1.
