Rollup merge of #110110 - lukas-code:display-panic-info, r=JohnTitor
Use `Display` in top-level example for `PanicInfo`
Addresses https://github.com/rust-lang/rust/issues/110098.
This confused me as well, when I was writing a `no_std` panic handler for the first time, so here's a better top-level example.
`Display` is stable, prints the `.message()` if available, and falls back to `.payload().downcast_ref<&str>()` if the message is not available. So this example should provide strictly more information and also work for formatted panics.
The old example still exists on the `payload` method.
