getAudioRoutes definition returns Promise<void>, but should return Promise<AudioRoute[]>

Bug report

• I've checked the example to reproduce the issue.

• Reproduced on:

• Android

• iOS

Above are essentially N/A, this is a definitions bug that is reflected in the code editor.

Description

index.d.ts currently lists getAudioRoutes() as returning Promise<void>. The readme suggests it should be returning Promise<AudioRoute[]>, correlated by the Java module.

Using getAudioRoutes thus requires a cast of getAudioRoutes() as unknown as Promise<AudioRoute[]> or similar.

The problematic line is located here:

https://github.com/react-native-webrtc/react-native-callkeep/blob/cc308ce2ed33bcc12ef1ef95468f4a81de7d6d4e/index.d.ts#L225

This appears to have been broken in this change: https://github.com/react-native-webrtc/react-native-callkeep/commit/0cba24edc969241dceee2ac2ea2817ceefe6d927#diff-7aa4473ede4abd9ec099e87fec67fd57afafaf39e05d493ab4533acc38547eb8

Steps to Reproduce

Use getAudioRoutes() in your code editor.

Logs

N/A

Start at index.d.ts around line 225 and compare the declaration with the getAudioRoutes documentation and the referenced Java module. Confirm that the editor exposes the documented return type and verify the corrected definition in a TypeScript usage example.
