Remove support for FormattedTextField (#2993)

### Background

Part of https://github.com/shop/issues-retail/issues/1955

TL;DR: FormattedTextField has been deprecated for the last major release, dropping support.

### Solution

This PR removes the deprecated `FormattedTextField` component from the Point of Sale UI Extensions. The component was previously marked as deprecated in favor of the `TextField` component. This change:

- Removes the `FormattedTextField` component implementation
- Removes related documentation and screenshots
- Removes the exported `AutoCapitalizationType` type
- Updates the versions documentation to note this breaking change

This completes the deprecation cycle by fully removing the component, ensuring developers use the recommended `TextField` component instead.

### 🎩

- Verified that the `TextField` component provides all the functionality needed to replace `FormattedTextField`
- Confirmed documentation properly directs users to the `TextField` component

### Checklist

- [x] I have 🎩'd these changes
- [x] I have updated relevant documentation
