chore: add "please simplify reproduction" comment (#52631)

### What?

Adding a new label comment for "please simplify reproduction".

### Why?

During triaging, a lot of time is gone into trying to isolate the actual bug being reported. Reproductions sometimes contain unrelated code - that sometimes can be the actual cause of an issue, reported as a bug in Next.js, or require third-party services, secrets, setting up databases, and other tasks that take up much of the resources before the issue can even be verified.

### How?

Similar to the `please add a complete reproduction` and `please verify canary` labels, if a maintainer adds the `please simplify reproduction` label, an automatic comment will appear on the issue, asking for a minimal reproduction
