[🔨common]: update the detail data of uip:configchange event

[yadamskaya]

The concern is that we dispatch the uip:configchange event with not processed data: name + value
The recommendation is to send processed and limited data.
Not:

{
  detail: {
     attribute: 'settings-collapsed',
     value: null
  }
}

But:

{
  detail: {
     config: 'settings-collapsed',
     value: false
  }
}

Or something like that

Or even simpler: dispatch the type of change but access the current value from the root directly.
