<!-- 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. -->

Currently, Vue modals do not emit `ionModal...` events. This happened
due to a change in the way the stencil output targets for Vue changed.
Christian [updated the
overlays](https://github.com/ionic-team/ionic-framework/pull/30227/files#diff-7e46aba01094c4917cd55e8eebd263fc4a297a2d62143f1ae30959ec4e023b6f)
to support the base events, but not the component-specific events.

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

With this change, you'll be able to bind to the events as described in
the Ionic documentation.
