Run ubuntu:22.10 image and install cargo-c package

In the current Docker ubuntu image (Ubuntu 22.04.1 LTS), I can't figure
out how to make the "cargo install cargo-c" command work:
1. The current version of cargo-c, 0.9.15+cargo-0.67, requires rustc
   1.66 or newer, but the rustc package is rustc 1.61.0.
2. Older versions of cargo-c, such as 0.9.14+cargo-0.66, allows rustc
   1.61.0, but it generates compilation errors in ignore v0.4.19:
   error[E0658]: use of unstable library feature 'scoped_threads'
3. It seems that only the 'nightly' versions of rustc can be made to
   allow unstable library features.

It turns out that cargo-c is available as a package in Ubuntu 22.10:
https://packages.ubuntu.com/search?keywords=cargo-c

Run the Docker ubuntu:rolling image, which currently points to Ubuntu
22.10: https://hub.docker.com/_/ubuntu/

Install cargo-c as a package.
