Merge #335

335: doc: Fix `arm-none-eabi-gdb` installation instruction for Fedora 27 or newer to just use `gdb` r=eldruin a=mavjs

- Fixes #249
- In the **Rust Embedded Discovery** book, it is noted to use `gdb` instead of `arm-none-eabi-gdb` as pointed out in rust-embedded/discovery#364 that `gdb` on Fedora justworks(tm). This was fixed for _Discovery_ book via rust-embedded/discovery#376
- Likewise, as mentioned per my comment in #249, on Fedora 37, `gdb` justworks(tm) as well.
