chore: bump rust-toolchain to fix test build (clap version mismatch)

[nulltea]

Build of tests in community-edition is failing because the latest version of clap required by criterion requires rust 1.74.

error: package `clap v4.5.0` cannot be built because it requires rustc 1.74 or newer, while the currently active rustc version is 1.73.0-nightly
Either upgrade to rustc 1.74 or newer, or use
cargo update -p clap@4.5.0 --precise ver
where `ver` is the latest version of `clap` supporting rustc 1.73.0-nightly

This PR bumps the version of rust toolkit to nightly-2023-11-16.
