feat: implement initial solution to incorporating DefaultFileMonitor …

…to LatexCitation (JabRef#10585)

Known Issues:

Sometimes throws ConcurrentModificationException from DefaultFileUpdateMonitor whenever a change occurs in the tracked directory

Does not have any kind of shutdown

Is not able to track changes in nested directories

Does not handle whenever a directory is changed from the initial one properly

Makes use of a Deprecated Class
