[FEATURE REQUEST] Improvement: accurate message in snackbar when copying/moving

[jesmrec]

That comes from #4802 (comment).

Current: generic message Items(s) copied/moved correctly

Improvement would be showing:

• Kind of item: file/folder/item (if both)
• Plurals
• Adding same setup to removal operation

(Idea of @mykh-hailo, thanks!!)
