HighTech Passport: committed 7 localized 'Developer Agreement' markdown files

HighTech Passport:

We committed changes to 7 'Developer Agreement' markdown files, in the following locales:
CS, DE, EL, HR, HU, pt-BR, SR-Latn

Please, be aware that in some locales, where the first line starts with a date in this format "DD. MMMM YYYY", the digits for the date (30) are interpreted by the markdown parser as an ordered list, and it shows like this "1.".
This is not a issue, it's just they way are parsed and displayed in GitHub.
Affected locales: CS, DE, HR, HU, SR-Latn.
