Remove Whitsunday (pentecost) from Austria

It's not a holiday:

@felixfrey Indeed Whitsunday is not an official public holiday in Austria, but is a major religious observance (As mentioned here https://publicholidays.at/pentecost/ and here https://www.timeanddate.com/holidays/austria/pentecost-sunday).

In Yasumi, Whitsunday is registered for Austria, but not classified as an official holiday. It is classified as "Observance", as you can see in the documentation https://www.yasumi.dev/providers/at.html#holidays and in the source code here:

yasumi/src/Yasumi/Provider/Austria.php

Line 58 in c747552

$this->addHoliday($this->pentecost($this->year, $this->timezone, $this->locale, Holiday::TYPE_OBSERVANCE));

.

So I don't think it needs to be removed.

@stelgenhof You are right. I missed the part of the documentation where it explains the filtering methods for holidays. That solves my use case and I hope the filter by type does not break anything for other countries in my code.
