revert upgrades of snakeyaml and jackson until compatibility updates made (1.6.x)

[miklish]

Issue: #1958

Recent commits to the light-4j 1.6.x branch have updated snakeyaml to 2.2 and Jackson to 2.15.3.

However, these dependency updates are not compatible with the current light-4j 1.6.x code-base.

Numerous code changes must be made to light-4j code base to make light-4j 1.6.x compatible with these updated dependency versions.

For example, snakeyaml 2.2 has changed numerous previously-zero-argument constructors to constructors that require arguments causing compilation failures. Jackson has deprecated certain TimeZone classes that are causing existing unit tests to fail.

The dependency version updates cannot be made alone without the code changes needed to make the codebase properly work with the changes in snakeyaml 2.2 and Jackson 2.15.3.

See discussions on the need for the downgrades here (snakeyaml):

I just merged snakeyaml PR. Now the light-4j 1.6.x is built.
