Description

This PR updates several dependencies in the Brave browser codebase, particularly around the gix family of crates and the rustls, hyper, and reqwest HTTP client libraries. The motivation seems to be bringing these dependencies up to their latest versions.

Changes

Changes

• Cargo.lock: Updated the versions and dependencies for numerous crates, including:
  • Updated gix crates like gix, gix-actor, gix-hash, gix-index, gix-object, gix-pack etc to newer versions
  • Bumped hyper from 0.14 to 1.3.1 and updated its dependencies
  • Upgraded reqwest from 0.11 to 0.12
  • Upgraded rustls from 0.21 to 0.22
  • Added some new indirect dependencies like ahash, atomic-waker
  • Removed some unused dependencies like btoi, num-traits, sct

Overall this is a substantial update to modernize the browser's Rust dependencies, especially around Git functionality, HTTP communication and TLS.

Security Hotspots

The main security sensitive updates are to rustls, hyper and reqwest which handle network encryption and communication. However, these are mature and widely used libraries, so upgrading to their latest versions is more likely to improve security than introduce new issues.

Reviewing the detailed changelogs for these to understand any breaking changes or new behaviors would be prudent from a security perspective. For example, understanding the implications of the rustls 0.21 to 0.22 upgrade. But overall these updates look reasonable from a security point of view.
