Not implemented islamic dates, you can convert gregorian to hijri calendar

Thanks! Can you rebase from main, so I can run the tests here?

@Nielsvanpach I did it. Can you run the tests?

Thanks, this PR looks good!
I'm still hesitant to merge countries with Islamic holidays. I would prefer to have a good solution on the lunar based holidays first.

Hi @Nielsvanpach

No library or built-in php intl functions convert dates properly for all years, including “geniusts/hijri-dates”. If you accept, it is most logical to prepare the dates between 1970 and 2037 as a constant class for Islamic holidays. Because Islamic holidays predicted and actual dates may change until the last moment.

Hi @Nielsvanpach

PR is done. Can you check please ?

No library or built-in php intl functions convert dates properly for all years or all country including “geniusts/hijri-dates”. It is most logical to prepare the dates between 1970 and 2037 as a constant property for Islamic holidays. Because Islamic holidays predicted and actual dates may change until the last moment. Since the information on wikipedia is incorrect, it was obtained by searching the old calendar on Google Images for each year. The accuracy of the information has been double checked. Ramadan and Sacrifice holidays vary for Turkey and other countries. A converter algorithm that will cover all years does not seem possible.

@Nielsvanpach Every year the celebration of ramadan and sacrifice holiday's dates are different in Turkey and even inside of the other Islamic countries that's why it's impossible to calculate because the countries are releasing the holiday dates six month ahead not years before. So can you merge this PR ?

Thanks for your work on this @thecaliskan !
