test(textarea): migrate to toHaveScreenshot (#28087)

Issue number: N/A

---------

<!-- 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. -->

Several tests for this component are still using Playwright's old
`toMatchSnapshot` assertion. It's now recommended to use the newer
`toHaveScreenshot` assertion. This new assertion reduces the size of
each screenshot and brings anti-flake improvements such as disabling
animations by default.

We previously migrated most of our codebase to use `toHaveScreenshot`,
but it looks like we missed the tests that were written during the
development of Ionic 7 in a separate branch off `main`.

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

- Migrate component tests to use `toHaveScreenshot`.

Note: There should be no layout changes to any of the screenshots. The
only difference between the old and new screenshots should be image and
file size.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
