chore: remove replay from issue template (#55397)
### What?
Removes Replay.io as a valid reproduction link from our bug template.
### Why?
Based on issues https://github.com/vercel/next.js/issues/55181 and https://github.com/vercel/next.js/issues/55278 it looks like people are struggling to report the correct thing. Also, without source maps, replays are still harder to use for debugging than an actual code base
