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. -->

Ionic Framework has fallback detection for Capacitor 2 applications to
avoid applying status bar style changes to the card modal.

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

- Ionic Framework's detection for applying status bar styles will be
based on the APIs available in Capacitor 3+.
- Ionic Framework will no longer support the legacy Capacitor 2
configurations.

## Does this introduce a breaking change?

- [x] Yes
- [ ] No

<!--
  If this introduces a breaking change:
1. Describe the impact and migration path for existing applications

  2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.
See
https://github.com/ionic-team/ionic-framework/blob/main/.github/CONTRIBUTING.md#footer

Developer should upgrade to the latest major release of Capacitor.

 - `accept` has been removed from the `ion-input` component. This was previously used in conjunction with the `type="file"`. However, the `file` value for `type` is not a valid value in Ionic Framework.
 - The `legacy` property and support for the legacy syntax, which involved placing an `ion-input` inside of an `ion-item` with an `ion-label`, have been removed. For more information on migrating from the legacy input syntax, refer to the [Input documentation](https://ionicframework.com/docs/api/input#migrating-from-legacy-input-syntax).

 - `getLength` returns `Promise<number>` instead of `<number>`. This method was not previously available in Nav's TypeScript interface, but developers could still access it by casting Nav as `any`. Developers should ensure they `await` their `getLength` call before accessing the returned value.
