Support GitHub rendering CSV
GitHub can render tabular data from .csv-Files. But it only supports comma-delimited files. So every .csv would need a change, and probably some changes in the backend are needed. I don't know whether the effort is worth the added value.
I changed one file as test. I also split up the German and English names in extra columns.
src/de/holidays/holidays.school.sh.csv
