Group rust toolchain and dockerfile updates

[dani-garcia]

🎟️ Tracking

📔 Objective

The rust version set in the memory-testing dockerfile is going out of sync with the one defined in rust-toolchain.toml. I've updated the renovate config to ensure they stay in sync, and that renovate will open a single PR for them.

Discovered here: #531

📋 Review Feedback

Renovate Configuration

The renovate configuration change is well-structured and follows best practices:

{
  "groupName": "rust",
  "matchManagers": ["custom.regex", "dockerfile"],
  "matchDepNames": ["rust"]
}

✅ Good practices observed:

• Correctly matches both custom.regex (for rust-toolchain.toml) and dockerfile managers
• Uses consistent naming pattern with existing rules
• Placed logically at the top of packageRules array

Current Version Mismatch

There's currently a version mismatch between:

• rust-toolchain.toml: 1.87.0
• crates/memory-testing/Dockerfile: 1.89-alpine

Resolution: Per author confirmation, this mismatch is intentional and will be automatically resolved by Renovate in the next update cycle after this PR merges. The new grouping rule ensures future updates stay synchronized.

---

✅ Recommendation

This PR is ready to merge. The configuration change achieves its stated objective of preventing future version drift between Rust toolchain and dockerfile specifications.
