Additional device check for Ipad Pro on Safari

[Drkjr92]

Description:
Issue raised in #5494.

The issue: iPadOS User Agent in Safari is same as on MacOS Catalina.

User case:

There are some use cases in which it is necessary to know whether it is a mobile device, e.g. a help dialogue that describes either touch or mouse/keyboard gestures.

Changes proposed:

• In isTablet() we want to extend the ipad check for those special cases where the user agent from the Ipad is labeled "MacOS"

Test also added and Results are shown below:
