Activation of "Show dedicated file columns" should add columns of existing files

[koppor]

Click:

Should automatically add all columns existing for the files attached. E.g., if a PDF is attached in any entry in the bib database, the column "PDF" should be added. If Word, then Word, ... - Do not add XLSX if no XLSX is attached

The columns should be added directly after the "file" column.

Implementation hint: The method exectued when putting the check mark is org.jabref.gui.preferences.TableTabViewModel#insertExtraFileColumns.

@koppor Should I remove this from the good first issues projects group, since you removed the label?

@ThiloteE Yes, please remove it. You can also delete our two comments then ^^
