feat(modal): update styles to iOS 17 specs (#28748)

Issue number: Internal

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

The card presentation of a presented view from a modal does not match
iOS 17 design.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Updates the transform scale of the presenting element with a modal to
have a similar width to iOS 17. In my discovery `0.91` is the closest
scale value.
- The presenting element refers to the view pushed behind the modal when
displayed with a card appearance.

The iOS reference is from the Events app, when creating a new event. The
Ionic reference is from the `modal/tests/card` example in the repository
(with the changes in this PR).
