Enabling catalogs update through renovate

[MKruschke]

Hi 👋🏻
First of all, thank you for this plugin — I happily stumbled across it and really appreciate how it enables catalogs similar to those in pnpm.

I’d like to contribute by adding support for Renovate so that dependency versions can be updated automatically.

My question:
Before I start, could you please let me know if you are planning any breaking changes that could impact this effort? It would help ensure that my contribution aligns with your roadmap.

Best Regards
Mirko
