Incorrect Isha angle in the preset of Umm al-Qura

[abougouffa]

Hello, first, I would like to thank you for this package.

I want to bring your attention to the preset of Umm al-Qura University

https://github.com/zkry/awqat/blob/1664c7e0403367ca2713115874d25fdcf661a990/awqat.el#L128-L130

In fact, the angle for Isha is not defined, Umm al-Qura do not use an angle based calculation for Isha.

Instead, it adds a fixed amount of time to the Maghrib time as follows:

• 90 minutes after Maghrib for all months except Ramadan.
• 120 minutes after Maghrib time during Ramadan.
