Update Malaysia holidays: add `th` localization

PPsyrius commented 6 days ago

Proposed change

Adds Thai (th) localization for Malaysia holidays (I did double-checked all typos this time).

[!NOTE] Thai Public Broadcasting Service (Thai PBS) is used as the primary source for Islamic holidays naming over Thai Wikipedia ones i.e. อีฎิ้ลฟิตริ instead of อีดิลฟิฏร์

For various royal wordings - Royal World Thailand's Title and Style Guide is used - the Sultan of Johor was conferred special title tier in Thai language compared to other Malaysian states, even without referring to his "Yang di-Pertuan Agong" status. [1] [2]

Type of change

[ ] New country/market holidays support (thank you!)
[x] Supported country/market holidays update (calendar discrepancy fix, localization)
[ ] Existing code/documentation/test/process quality improvement (best practice, cleanup, refactoring, optimization)
[ ] Dependency update (version deprecation/pin/upgrade)
[ ] Bugfix (non-breaking change which fixes an issue)
[ ] Breaking change (a code change causing existing functionality to break)
[ ] New feature (new python-holidays functionality in general)
