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

<!-- 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. -->
On iOS when dismissing the `ion-action-sheet`, the animation does not
account for the safe area of the device. This results in the action
sheet not completely animating off the visible viewport on a device with
safe area enabled.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- The `ion-action-sheet` will animate consistently off the viewport when
dismissing, including the safe area.
To better support custom animations not needing to account for the safe
area, the safe area has been added to the padding of the action sheet
container. This results in the height increasing based on the bottom
safe area and animating correctly when translating between [`100%` and
`0%`](9d57758e3e/core/src/components/action-sheet/animations/ios.enter.ts (L23)).

In the recorded examples the bottom safe area is exaggerated to show the
dismiss animation differences.
## Does this introduce a breaking change?
- [ ] Yes
- [x] No
<!--
If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.

## Other information
<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
To test this PR, I would recommend adding the following styles to the
action sheet basic test:
```html
<style>
ion-action-sheet {
--ion-safe-area-bottom: 100px;
}
</style>
```
You can then open dev-tools and slow the animation speed to 10%:

- Open and dismiss the action sheet tied to the "Basic" button.
- Verify that the action sheet animates completely off the view when
dismissed.
- Open the and dismiss the action sheet tied to the "Custom CSS Class"
button. This implementation customizes the `--height` of the action
sheet.
- Verify that the action sheet animates completely off the view when
dismissed.
