Move static checks to single-line ones (#27424)

Suddenly github stopped liking 3-years old (otherwise perfectly fine)
double-quoted mutli-line strings indented in the way that they
lacked spaces (even it is perfectly valid yaml). Seems they
changed parser to be a lot more picky (and rather wrong because such
multi-line entries when ended with \ are perfectly fine according to
yaml specification.

This change fixes the problem by making those keys single line and
telling yamlling to ignore their length (yammlint was the main
reason why they were converted into multi-line keys).
