ci: bump nightly version

[AaronFeickert]

Description

Consistent with other repositories in the ecosystem, this PR bumps the nightly toolchain to nightly-2024-02-01. It addresses many updated lints.

Motivation and Context

Other repositories are pinning their nightly toolchains at nightly-2024-02-01 due to a curve library issue. It seems like a good time to bump the nightly version here as well.

There are two warning lints that identify Arcs whose underlying types are not Send + Sync. It's unclear if it's safe to ignore these.

After discussion, it sounds like while an eventual update to the nightly toolchain may be useful to avoid ongoing technical debt (and in case of a future curve library update), it isn't particularly crucial at this time.

Closing.
