fix: update riscv-rt to avoid yanked version

[sethp]

Even with the changes in esp-rs/esp-hal#350 creating a new project from the template for an esp32c3 produces a result that fails to build with:

error: failed to select a version for the requirement `riscv = "^0.9"`
candidate versions found which didn't match: 0.10.1, 0.8.0, 0.7.0, ...
location searched: crates.io index
required by package `riscv-rt v0.10.0`
    ... which satisfies dependency `riscv-rt = "^0.10"` of package `example_project v0.1.0 (/home/seth/Code/src/github.com/rustbox/esp-hal/example-project)`

Additional correction is needed to compile. It's necessary to remove unwrap().

error[E0599]: no method named `unwrap` found for struct `Peripherals` in the current scope
 --> src/main.rs:9:43

9 |     let peripherals = Peripherals::take().unwrap();
  |                                           ^^^^^^ method not found in `Peripherals`

Thanks @georgik : that's what I get for trying to avoid learning how to work with cargo generate from a local path!

Fifth time's the charm, I guess?

Hi, thanks for your contribution! New hals just got released and the template is now updated and working properly again!
