Request to Update MJPC's Dependency to Support Latest MuJoCo Features

Hi,

MuJoCo versions 3.2.0+ introduced powerful features like the `mjSpec` API for dynamic model updates, and 3.2.5 added functionalities like `mjs_attachToSite`. These enhancements make it easier to modify simulations dynamically without disruption.

Currently, **MJPC requires MuJoCo 3.2.3**, while **the latest version is 3.2.7**, which includes even more improvements. Would it be possible to update MJPC to support the latest MuJoCo versions and leverage these capabilities?

Thank you for your consideration.

Best regards,
Dimitris
