fix (kubernetes-client-api) : Change SnakeYaml's implicit resolver me…

…thod signature

We don't seem to have any direct dependency on SnakeYaml. It's coming as
transitive dependency from Jackson Dataformat Yaml.

In Jackson 2.13.3 SnakeYaml 1.30 was being used. In 2.13.4, SnakeYaml
1.31 is getting used which seems to have some changes with respect to
resolvers limits. Modifying CustomYamlTagResolver used in serialization
with respect to new version.
