Wouldn't we want to assume lowest version instead of highest if there isn't one specified?

AFAIK, the only scenario where it is undefined is in some test cases for this pass that don't fully configure the ComponentDocumentClassifierPass with parser options. For that scenario, I figured it made sense to update to the latest.
Assuming this happens to a user, I think it also makes sense to default to the latest since the constrained type param directive can still support unconstrained scenarios.

Fixes #32592 and fixes #32193 and probably also fixes #32237.
The way the
TypeParamDirectivewas instantiated before ran the risk of having an undefinedDirectiveproperty if multiple project engines are instantiated. This is more likely to happen in tests that run in parallel and in our compilation flow.I've cleaned this up so that the correct
TypeParamDirectiveconstruct is produced depending on the language version.
