[Feature] add a "delete script" on the script tab accessible with a right click

### Feature Description
Right click on the tab of a script to delete it  (would be also great to enable/disable it)

### Use Case

Since  I duplicate heaviliy my scripts  and change their name subtily I often struggle to find the right one to delete. It would be much easier (and intuitive) to delete them directly by right clicking on its tab.  (Would be also great to enable/disable it).
