Resolve tap to pay connected account issue on iOS

Description

This pull request contains the fix for the following related issue raised a couple of weeks ago: https://github.com/BreX900/mek-packages/issues/50

It appears that the reason why tap to pay wasn't working for connected accounts was due to not being able to set the connected account id when instantiating LocalMobileConnectionConfigurationBuilder in the onConnectMobileReader method in Terminal.swift.

The onConnectMobileReader method not accepts an onBehalfOf field which is sent to the configuration builder:

// stripe_terminal/ios/Classes/TerminalPlugin.swift

func onConnectMobileReader(
        _ serialNumber: String,
        _ locationId: String,
        _ autoReconnectOnUnexpectedDisconnect: Bool
        _ autoReconnectOnUnexpectedDisconnect: Bool,
        _ onBehalfOf: String? // <-----
    ) async throws -> ReaderApi {
        let config = LocalMobileConnectionConfigurationBuilder(locationId: locationId)
            .setOnBehalfOf(onBehalfOf) // <-----
            .setAutoReconnectOnUnexpectedDisconnect(autoReconnectOnUnexpectedDisconnect)
            .setAutoReconnectionDelegate(_readerReconnectionDelegate)
 ...
...

On the Flutter side the platform api method now looks like this:

// stripe_terminal/lib/src/platform/terminal_platform.dart

Future<Reader> connectMobileReader(
    String serialNumber, {
    required String locationId,
    required bool autoReconnectOnUnexpectedDisconnect,
    String? onBehalfOf, // <------
});

To confirm I did run the following command for generating the code to communicate between Flutter and Android/iOS platforms:

dart run tool/generate_api.dart

Any news on this? I need to send the "onBehalfOf" parameter. Thanks

@jermaine-uome Can you format dart files with 100 page width? Also for commits follow the convention: https://www.conventionalcommits.org/en/v1.0.0/
