Added NSMicrophoneUsageDescription

[bozidarsevo]

Closes: #14174

Description

There was a crash happening because NSMicrophoneUsageDescription was missing. In the app we were not using microphone but @rachelmcr was able to find the problem. If you go to wp-admin from the app and try to add Media from there it will crash when taking a video.

With this PR, NSMicrophoneUsageDescription is added and the crash is fixed!

Steps to reproduce

• Go to the Hub Menu.
• Open WooCommerce Admin.
• In the admin dashboard, open the site’s Media section.
• Tap the button to add new media.
• Select “Take Photo or Video.”
• In the device camera, switch to Video.
• Without this PR fix it should crash

Testing information

• Go to the Hub Menu.
• Open WooCommerce Admin.
• In the admin dashboard, open the site’s Media section.
• Tap the button to add new media.
• Select “Take Photo or Video.”
• In the device camera, switch to Video.
• With this PR it should not crash and you are able to record and add the recorded video
