Prerequisites

• [X] I have read the Contributing Guidelines.
• [X] I agree to follow the Code of Conduct.
• [X] I have searched for existing issues that already include this feature request, without success.

Describe the Feature Request

The clear button on the ion-searchbar has an aria-label of "reset" (code here), which is not clear enough for screenreader users. The label should be more descriptive, perhaps “clear search input”.

Describe the Use Case

"Reset" may be unclear to screenreader users, and so the button's aria-label should be more descriptive.

Describe Preferred Solution

Two possible solutions:

1. Add a prop so that consuming applications can optionally pass their own aria-label for the searchbar's "clear button".
2. Update the existing aria-label (here) to be something more descriptive, like "clear search input".

Thank you!!
