Update Renovate configuration to respect manually curated dependency ranges

[harryswift01]

Summary

This PR updates the Renovate configuration to use the in-range-only strategy for dependency updates. The goal is to ensure manually curated version ranges are respected, avoiding automatic replacement or widening, while still updating lockfiles for in-range versions and notifying about out-of-range releases.

Changes

Update rangeStrategy to in-range-only

• Replaces "rangeStrategy": "replace" with "rangeStrategy": "in-range-only".
• Ensures Renovate respects manually defined version ranges in pyproject.toml.

Enable dependencyDashboard

• Adds "dependencyDashboard": true to the configuration.
• Allows out-of-range updates to be visible in the dashboard without automatically merging them.

Impact

• Renovate will no longer pin dependencies outside manually curated ranges.
• Lockfiles for in-range versions will continue to be updated automatically.
• Out-of-range updates will be visible for review, reducing the risk of breaking CI or the codebase.

We see that this configuration behaves the way we wanted on the aiida-gromacs repository. So this is a good addition here too.

Looks great and is proven on two other repos now.
