fix: include io.IOBase in the PathType

[sycai]

Add io.IOBase to the PathType.

Reasons:

• Our code allows and explicitly checks IOBase input:

  python-bigquery/google/cloud/bigquery/client.py

  Line 4334 in fa76e31

  ifisinstance(destination, io.IOBase):

• In Google3 we have this type too

There's no reason that PathType in the GitHub version does not include io.IOBase

fix: #452403174 🦕

System test failure appears unrelated.
