(camera) Multiple selection not working on some Android devices

[dragermrb]

Bug Report

On android, method pickImages() (and pickImage() too) uses Intent.ACTION_PICK with extra data Intent.EXTRA_ALLOW_MULTIPLE set to true, but ACTION_PICK is not documented to support EXTRA_ALLOW_MULTIPLE.

Specifically:

• The documentation for ACTION_PICK does not mention any supported extras
• The documentation for EXTRA_ALLOW_MULTIPLE only mentions ACTION_GET_CONTENT and ACTION_OPEN_DOCUMENT

Selecting multiple photos on some devices (Oppo/Realme for example) doesn't work.

Switch Intent.ACTION_PICK to Intent.ACTION_OPEN_DOCUMENT can solve the problem.
