Address Cargo Deny findings

[geraname]

Thank you for submitting this pull request. We really appreciate you spending the time to work on SurrealDB. 🚀 🎉

What is the motivation?

To unblock #5170 by ensuring that Cargo Deny succeeds in CI.

What does this change do?

• Remove or update use of the deprecated fields by Cargo Deny in:
  • Deprecate several fields EmbarkStudios/cargo-deny#606
  • Add version = 2 EmbarkStudios/cargo-deny#611
  • vulnerability no longer does anything and deny is the default.
  • unmaintained, notice and severity-threshold no longer do anything.
  • default for licenses is now always deny for all new values.
  • unlicensed and copyleft are now treated as any other license.
• Updates rustls to 0.23.18 to address RUSTSEC-2024-0399.
  • This issue does not affect SurrealDB, we do not use rustls::server::Acceptor::accept().
• Allows the CDDL-1.0 license, which is used by the inferno crate, required by pprof.
  • This needs approval by @tobiemh after legal review.
