Auto rename files feature fix for #11316

[wtfjjking]

Added a new option [ ] Auto rename files if entry changes under Preferences -> Linked files -> Linked file name conventions, with the default value set to false. When this option is enabled, JabRef will automatically rename files if the filename matches the defined naming pattern.

Users requested that JabRef automatically rename files when entry data is changed, provided the filename matches the defined naming pattern. This feature improves file management automation and reduces the need for manual intervention.

I change the data also changing the name generated the defined pattern
JabRef should rename the file, too
hello may i ask what exactly the task mean, is it mean that i link a file to an entry, and then i change the file name in the optional fields, then the file name itself also changed, but currently there is no filename in the optional fields, so I should add one, and then implement the logic
