create shortcut menu on linux

### Description

since offered linux version is a zip file, would be good to add an option to install/uninstall laucher into user (gnome/kde/xfce/etc) menu.

to do so an option in tools menu would offer to install netbeans .desktop launcher under `~/.local/share/applications/` and then invoke `update-desktop-database` as seen [here](https://unix.stackexchange.com/a/565807/143289)

### Use case/motivation

The lack of a desktop entry menu option puts netbeans as a second-class citizen on linux desktops

### Code of Conduct

Yes

Start at the NetBeans Tools menu and trace how Linux-specific actions are implemented. Use the requested ~/.local/share/applications/ location and the update-desktop-database command as the behavior to investigate. Done means the user can install and uninstall a NetBeans .desktop launcher from the menu for common Linux desktops.
