/**
 * Property level decorator. Specifies if a property should have a phone number format.
 * String properties named `phoneNumber` automatically get this format unless they are marked with
 * `@preventDefault()`.
 *
 * For example, `phoneNumber?: string` is automatically formatted as a phone number and displayed
 * like `(555) 121-2122`. A differently named property, such as `mobilePhone?: string`, is displayed
 * as raw text like `5551212122` unless you add `@phoneNumber()`.
 *
 * Sets `{@link PropertyMeta.phoneNumber}`.
