[@mantine/modals] Expose Modals Manager props

[pfo-omicsstudio]

I had a use case in my application where I needed to read from the Modals manager props, so I created this PR to allow them to be exposed to the user.

EDIT: I also discovered an error in my implementation of updateContextModal, which would throw the following error:
hook.js:608 Warning: React does not recognize the `modalId` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `modalid` instead. If you accidentally passed it from a parent component, remove it from the DOM element. Error Component Stack

This occurred because the modalId was unintentionally included in the props passed to the modal component. I have resolved this in the PR by ensuring that modalId is excluded from the props spread onto the modal.
