Save opened tabs / session every 5 minutes or so

### Description

Please save the current session every now and then (e.g. every 5 minutes). Perhaps number of minutes could be an option in prefs.

Currently, when the app crashes, all my tabs are gone. So saving only during closing is not sufficient. It would be really great to have peace of mind.

### Use case/motivation

All my tabs are gone after NB crashes. There might be various causes, but for me, it was issues with AWT like the ones described here: https://github.com/apache/netbeans/issues/8236 and possibly related: https://github.com/adoptium/adoptium-support/issues/1203.

The system might crash occasionally too. There might be a power outage (sometimes long enough that even the UPS battery isn’t sufficient).

No

No files or tests are named. Start by tracing where NetBeans saves the current session during application closing and where preferences are defined; then determine how periodic saving and its interval would fit those existing paths. Done means tabs and session state can be recovered after a crash or power loss, with the interval configurable if supported.
