test: remove weirdly broken test case

if you have one file that has both `/(\d)/` and `/\d*(\d)/` in it, the
second pattern's regexplanation will *sometimes* erroneously repeat the
heading "capture group 1", but you can clear this up by hovering a
different regexp first

This case is weird enough that I'm choosing to ignore it for now
