esp32c3-hal riscv-rt should be updated to 0.11.0 to avoid now yanked riscv 0.10.0 and 0.9.0

[dougli1sqrd]

It looks like the riscv crate was updated to 0.10.1 and versions 0.9.0 and 0.10.0 were yanked from crates.io. The riscv-rt crate was also updated to 0.11.0 to depend on riscv 0.10.1.

Let's update the esp32c3-hal to depend on riscv-rt 0.11.0 to no longer depend on the missing riscv 0.9.0 crate.

In my Cargo.toml:

esp-hal-common = { git = "https://github.com/esp-rs/esp-hal", features = ["esp32c3"], rev = "4d036c3" }
esp32c3-hal = { git = "https://github.com/esp-rs/esp-hal", features = ["direct-boot"], rev = "4d036c3" }

$ cargo build
