[BUG] Rust Hello example with cargo fails to build

### Description / Steps to reproduce the issue

I'm trying to build that with latest rust compiler and gives an error:

```
error: panic_immediate_abort is now a real panic strategy! Enable it with `panic = "immediate-abort"` in Cargo.toml, or with the compiler flags `-Zunstable-opti
ons -Cpanic=immediate-abort`. In both cases, you still need to build core, e.g. with `-Zbuild-std`
