Update Rust to 1.80.0

[arpad-m]

We keep the practice of keeping the compiler up to date, pointing to the latest release. This is done by many other projects in the Rust ecosystem as well.

Release notes.

Prior update was in #8048

Should we also update a Dockerfile for build-tools image?

neon/Dockerfile.build-tools

Line 195 in bea0468

ENV RUSTC_VERSION=1.79.0

hmm legit error link:

according to this, it's a known breakage and it's recommended to update the time crate. The latest pg_jsonschema still doesn't have it yet, so I added a cargo update statement for the time crate.

edit: it seems to affect unrelated PRs as well, as we always take the latest stable rust release in that dockerfile:
