[Bug]: NativeBridge doesn't pass responseType to native HTTP

[SillyButt]

Capacitor Version

@capacitor/cli: 5.6.0 @capacitor/core: 5.6.0 @capacitor/android: 5.6.0 @capacitor/ios: 5.6.0

Other API Details

npm: 10.5.0
node: 20.9.0

Platforms Affected

• [X] iOS
• [X] Android
• [ ] Web

Current Behavior

When using http requests via patched by Capacitor's native-bridge XHR/Fetch with expected responseType, the Bridge doesn't pass responseType to Native HTTP (Android/iOS). This leads to Native HTTP to not process the data with expected response type.

Example: A request with responseType: 'blob' will not be treated by native HTTP as Blob and encoded to base64 rather than a plain string, despite responseType to be expected in native bridges code on Android and iOS side.

Expected Behavior

Requests with responseType: 'blob' should return Blob with valid type.
