fix: relax dataclasses-json upper bound from <0.5.12 to <0.6.0

The <0.5.12 cap was added when 0.5.12 dropped the marshmallow-enum
transitive dependency. Since flytekit now declares marshmallow-enum
as a direct dependency, 0.5.12–0.5.14 are safe. The <0.6.0 cap
remains because 0.6.0 removes marshmallow-enum support entirely
in favor of native Enum, which breaks type_engine.py.
