Escaped Backslashes gets unescaped

[YasserGersy]

I have the following yaml

    matchers:
      - type: status
        status:
          - 200
          - 400
        condition: or
      - type: regex
        regex:
          - "((u|g)id|groups)=[0-9]{1,4}\\([a-z0-9]+\\)"
        part: body

Which gets deserialized to an object of matchers : when i invoke matchers[0].regex[0]: it returns a different value , the pattern was unescaped to :

((u|g)id|groups)=[0-9]{1,4}\([a-z0-9]+\)

Which has a different meaning.

In the spec, section 5.7,

Note that escape sequences are only interpreted in [double-quoted scalars](https://yaml.org/spec/1.2.2/#double-quoted-style). In all other [scalar styles](https://yaml.org/spec/1.2.2/#node-styles), the “\” character has no special meaning and non-[printable](https://yaml.org/spec/1.2.2/#character-set) characters are not available.

This is expected. To get this to work you would need to escape those escape characters, \\\\. Re-open this issue if that doesn't solve your problem.
