fix(evals): Change eval set discrimination strategy

[andrei-rusu]

This PR makes the routing to the new model of EvalSets to occur based on whether the version field is present and its value can be cast to a float that is >=1.
Currently. the new EvalSets would error if one gives another version than 1.0 in the JSON because the version field is enforced to be a Literal["1.0"]. To test this PR, we amended locally the pydantic class to allow for other versions. Yet, on main, other versions than 1.0 would fail until another PR amends this restriction.
