fix(ci): cargo update to evict the cache

[CommanderStorm]

After looking into how our CI works, this needs an actual dependency bump to bust the cache.

Also, the rerun-if-env-changed can in this case be replaced with option_env

Pull Request Overview

This PR bumps dependencies to bust the cache and updates the build script to use a compile‐time check for the RUSTDOC environment variable instead of the runtime approach.

• Removed the outdated cargo directive that triggered re-run of the build script via an environment variable.
• Replaced runtime environment variable check with a compile-time option_env! call.

• The removal of the cargo directive that triggers the build re-run when RUSTDOC changes may affect cache busting behavior. Please verify that switching to a compile-time option_env! check achieves the intended effect without impacting build script re-run triggers.
