Add a confirmation modal for relation object deletion (#8818)

Fixes #8698 

1. Summary
We decided to add a confirmation modal for the relation object deletion.
It's gonna a bit of safety to the user interactions because this action
can be disruptive even though it can be restored.

2. Solution
Used `createPortal` function to address the issue where the vertical
scrollbar shows over the modal. Added a logic that displays a
confirmation modal for deletion in [this
file](d284419d66/packages/twenty-front/src/modules/object-record/record-show/record-detail-section/components/RecordDetailRelationRecordsListItem.tsx).
I can update the text(title, description, and CTA) as necessary based on
the feedback.

_**However, I observed an issue that the deleted object still shows up
under the list until hard-refresh. I figured that can be addressed as a
separate issue.**_
