Circuit diagrams: Show source code links for grouped operations

[minestarks]

Enables source code links for grouped operations, just as with simple gates.

I noticed two things while playing around with this:

1. If I collapse all of a circuit to the Main operation, that Main box is not clickable despite the fact that there is a Main operation that it could navigate the user to.
2. The expand/collapse state of a group is not preserved when collapsing a surrounding group. If A calls B, there will be a group A that, when expanded will show a collapsed group B. If I then expand the group B and collapse and re-expand the surrounding group A, B does not remember that it was expanded and shows as collapsed instead.

The expand/collapse behavior is a bit of a mess. Frankly I've had trouble figuring out what the "correct" behavior even should be - from your description, this sounds normal to me, but maybe it feels awkward in practice. Do you happen to know if what you're seeing is new in this PR, or is it the same in main? (I can check if you don't know).

The behavior didn't change with this PR, so it is consistent with what is in main.

@ScottCarda-MS I have some expand/collapse behavior refinement in the works - stay tuned!
