Light bulb should be greyed out after the line/keybinding is no longer active

Testing #166761

In the editor, users are trained that whenever they see a lightbulb, they can ctrl+. for a quick fix. However, in a terminal, we can show a lightbulb for a previous line:

This light bulb can still be clicked on, but the keybinding doesn't work here. I suggest greying out (or removing) the lightbulb in this case.

This is a special case where if no command is run, the previous quick fixes are still available, for example if you double hit enter. It's correct that it's yellow but the keybinding should definitely still be working.

The keybinding still works for me even after i've hit enter a few times
