Subject: [RFC PATCH] docs: rust: quick-start: add Ubuntu

Ubuntu has changed their maintenance model for Rust toolchains and is
now providing recent Rust releases in their releases, including both
LTS and non-LTS (interim) releases.

Therefore, add instructions to the Quick Start guide for Ubuntu like
for the other distributions.

This is a potential patch for the future -- Ubuntu Oracular (future
release) works today, but the Rust versioned releases are not backported
(yet?). If Ubuntu ends up deciding to backport them, which would be
amazing, or at least when they start to appear in an actual release,
then we can apply this. Thanks William & Zixing!

+Ubuntu LTS and non-LTS (interim) releases provide recent Rust releases and thus
+they should generally work out of the box, e.g.::
+
+	apt install rustc-1.80 rust-1.80-src bindgen-0.65 rustfmt-1.80 rust-1.80-clippy
