Import the right BaseOperator in baseoperatorlinks

Ran into this issue on my PR:

providers/microsoft/azure/src/airflow/providers/microsoft/azure/operators/synapse.py:156: error:
Argument 1 of "get_link" is incompatible with supertype "BaseOperatorLink";
supertype defines the argument type as "BaseOperator"  [override]

Caused due to recent change: #46415

Changing back to the correct BaseOperator from models. We will make the move when we start moving providers to use task sdk cc @ashb

I guess if this fixes it that's fine for now, but I don't think this is the "best" long term fix

[amoghrajesh]

Definitely not. But we should start making this change once we start moving providers to use task sdk imports. That way providers will not have a airflow.models import

This isn't running mypy-providers so I'm merging this now anyway
