Downgrade Rust Docker image from 1.85.0-bookworm to 1.84.0-bookworm to restore missing dependencies

[kbukum1]

What are you trying to accomplish?

Downgrading the Rust base image from rust:1.85.0-bookworm to rust:1.84.0-bookworm to fix missing dependencies in the Cargo ecosystem.

Why?

The rust:1.85.0-bookworm Docker image is missing required layers, leading to issues where cargo is not found in the container environment. This has been confirmed by reverting locally and testing cargo commands successfully.

Issue Link: dependabot-core/issues/11737
Sentry Issue: DELTAFORCE-12XK

Anything you want to highlight for special attention from reviewers?

• This downgrade is a temporary fix to restore functionality.
• Further investigation may be needed to determine why rust:1.85.0-bookworm is missing essential dependencies.
• If a better long-term solution is found, we may consider upgrading in the future.

How will you know you've accomplished your goal?

• Running cargo commands inside the container should work as expected.
• CI/CD tests should pass without any dependency-related failures.
• The error reported in the linked issue should no longer occur.
