Update dependencies and resolve workflow failures

[Swaagie]

Thought this might be a meaningful first contribution, updated dependencies and opted out of using the chrono crate for the hello_world example. I have no experience with bazel/raze before (up until now) so if I'm making crazy changes please let me know.

• Updated cargo-raze to 0.14.1 (and adjusted build configs)
• Updated to use rust edition 2021 as cargo metadata depended on latest without having to use nightly.
• Removed chrono crate in favor of time crate to avoid having to wait for a resolution for the sec vun
• Updated rust_rules to b3ddf6f096887b757ab1a661662a95d6b2699fa7
• Fixed clippy suggested safe read of potentially unallocated memory with MaybeUninit
• Regenerated lockfiles

Happy to change and update the PR where needed.

Thanks, this looks fine, but could you please split this into multiple self-contained PRs?

[Swaagie]

Certainly, let the cherry picking commence 😄

Closing this in favor of smaller isolated PRs as requested
