update version & changelog

## 3.0.0-beta.4
Fixes:
* Fixes a permission bug on Android where denying the permission would cause an infinite loop of permission requests.
* Updates the example app to handle permission errors with the new builder parameter.
Now it no longer throws uncaught exceptions when the permission is denied.
Features:
* Added a new `errorBuilder` to the `MobileScanner` widget that can be used to customize the error state of the preview.
## 3.0.0-beta.3
Deprecated:
* The `onStart` method has been renamed to `onScannerStarted`.
