copy button in the history dialog should probably have feedback?

so so far in gnome i've seen two kinds of copy controls:

• "Copy" as an item in a popup menu (for example the right-click menu on a text field), clicking which closes the menu
• a 📜Copy button outside of a popup menu, which opens a toast saying that the data was copied

in both cases the screen changes after you click it, but in the history dialog, when you click the copy button on the end of a row, nothing changes on the screen (except for the press animation), so it may kind of feel like nothing actually happened when you pressed it.

imo it should open a toast saying "Link copied", wdyt?
