Add national holidays for Malta in both English (en-gb) and Maltese (mt)
This MR adds two files:
- holiday_mt_en-gb: Maltese National Holidays, British English
- holiday_mt_mt: Maltese National Holidays, Maltese
Sources of reference: Official Table of National Holidays on the Malta Government site: https://www.gov.mt/en/About%20Malta/Pages/Public%20Holidays.aspx Actual legal text: https://legislation.mt/eli/cap/252/eng/pdf
For Maltese versions please see the bilingual options on the links above.
Syntax correctness was tested as per README.md instructions. See attached log: kholidays_debug.log
I noticed support for Maltese holidays doesn't exist and because I missed my holiday planning I decided to take things into my own hands and rectify this situation :) Starting with kholidays seemed like the easiest thing to do.
