fix: replace serde_yaml with serde_yaml_ng

[vlada-dudr]

1. Does this PR affect any open issues?(Y/N) and add issue references (e.g. "fix #123", "re #123".):

fixes #1986

2. What is the scope of this PR (e.g. component or file name):

I replaced vendored serde_yaml with maintained fork of it - serde_yaml_ng, which looks like being used by quite some projects.

When running tests, the failed ones are exactly same as on main.

[vlada-dudr]

Ok, so i fixed that failing test. It seems that serializer behaviour changed. Now it looks like it produces unquoted strings for yaml 1.1 booleans - string "on" serializes as on (previously it was 'on'). I guess it may be problematic when consumer of such string is yaml 1.1 compliant.
