`FacilityPort.show()` errors out

[sajith]

Copying the error seen in a notebook:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[4], line 1

File [~/fabrictestbed-extensions/fabrictestbed_extensions/fablib/facility_port.py:101](https://jupyter.fabric-testbed.net/home/fabric/fabrictestbed-extensions/fabrictestbed_extensions/fablib/facility_port.py#line=100), in FacilityPort.show(self, fields, output, quiet, colors, pretty_names)
     98 def show(
     99     self, fields=None, output=None, quiet=False, colors=False, pretty_names=True
    100 ):
--> 101     data = self.toDict(pretty_names=True)
    103     # fields = ["Name",
    104     #         ]
    106     if pretty_names:

TypeError: FacilityPort.toDict() got an unexpected keyword argument 'pretty_names'

Seems the fix should be trivial. But I have not been able to properly test FacilityPort.show(), because of errors when creating a slice using the example notebook (see below, with some wrapping added in the message text for better readability), so just leaving this issue report for now.
