Auto merge of #88631 - camelid:sugg-span, r=davidtwco

Improve structured tuple struct suggestion

Previously, the span was just for the constructor name, which meant it
would result in syntactically-invalid code when applied. Now, the span
is for the entire expression.

I also changed it to use `span_suggestion_verbose`, for two reasons:

1. Now that the suggestion span has been corrected, the output is a bit
   cluttered and hard to read. Putting the suggestion its own window
   creates more space.

2. It's easier to see what's being suggested, since now the version
   after the suggestion is applied is shown.
