Update cargo/rust to 1.85

[Stevenjin8]

Is your feature request related to a problem? Please describe.
I'm trying to build ztunnel on Azure linux which uses rust edition 2024. The current version on azlinux (1.75.0-11) does not support edition 2024

Describe the solution you'd like

rust 1.85.0

Describe alternatives you've considered

Additional context

Here is what happens when I try to build in an azl3 container

root [ /ztunnel ]# cargo build
error: failed to parse manifest at `/ztunnel/Cargo.toml`
 
Caused by:
  feature `edition2024` is required
 
  The package requires the Cargo feature called `edition2024`, but that feature is not stabilized in this version of Cargo (1.75.0).
  Consider trying a newer version of Cargo (this may require the nightly release).
  See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2024 for more information about the status of this feature.
