In YAML >= 1.2 duiplicated keys, even `>>` are not allowed [1], and should lead to errors like `Duplicate merge keys are never allowed`. While PyYAML still can parse sunch formatting, ruamel.yaml will fail right away on attempt to read/write to such file. Let's remove pre-YAML 1.2 examples from our documentations to ensure compatability.
