Deprecated SnakeYAML methods (#3079)

I replaced the deprecated methods in SnakeYAML 1.33 with the respective non-deprecated constructor calls.
These are equivalent:
The deprecated non-arg constructor of Constructor https://bitbucket.org/snakeyaml/snakeyaml/src/snakeyaml-1.33/src/main/java/org/yaml/snakeyaml/constructor/Constructor.java
calls https://bitbucket.org/snakeyaml/snakeyaml/src/7f5106920d7754ecab734725ba577083e55c7204/src/main/java/org/yaml/snakeyaml/constructor/SafeConstructor.java#lines-52, which uses a new empty LoaderOptions()

Similarly, SafeRepresenter https://bitbucket.org/snakeyaml/snakeyaml/src/7f5106920d7754ecab734725ba577083e55c7204/src/main/java/org/yaml/snakeyaml/representer/SafeRepresenter.java#lines-54 uses a new empty DumperOptions.
