Add ability to jump to signal source from the "Connections to method" dialog

Godot 4.2.2

Sometimes I want to start from a function and trace the signal from that function to the node the signal originated from.

However, if I click the green arrow next to the function to see the connected signals (in the "Connections to method" dialog) the information there is not sufficient for me to find where the signal originates. For example, the Source might be listed as "Button", or "ButtonToggleUI" if I renamed it, but just knowing a node's name doesn't help me find it.

I have two suggestions for solutions:

1. on hover, show the full path of the Source, eg "game.tscn/Game/UI/ButtonToggleUI", or, even better:
2. on click, load the correct scene, open the correct branch, and highlight the Source node, moving from Inspector to Node/Signals and highlighting the signal
