fixes:

Fixed an issue with the :class:`~.VF2Layout` pass where it would error
when running with a :class:`~.Target` that had instructions that were
missing error rates. This has been corrected so in such cases the
lack of an error rate will be treated as an ideal implementation and
if no error rates are present it will just select the first matching
layout.
Fixed `#8970 <https://github.com/Qiskit/qiskit-terra/issues/8970>`__

Fixed an issue with the :class:`~.VF2PostLayout` pass where it would
error when running with a :class:~.Target` that had instructions that
were missing. In such cases the lack of an error rate will be treated as
an ideal implementation of the operation.
