Typo in error message in the PlanePlot class

[pjk645-zz]

The error message should probably read: ' requires an x and a y column' not ' requires and x and y column'

pandas/pandas/plotting/_core.py

Line 814 in 0c65c57

raise ValueError(self._kind + ' requires and x and y column')

Thanks - want to submit a PR to fix?

I'm afraid I'm not set up to pull because of my work's firewall and lack of a computer at home (just a smart phone). Maybe I can do it from my phone, but I'm a newbie, so...

@pjk645 you can surely do it via smartphone (but it is gonna be a little tedious).

Marking this for 0.24.0 to give time for someone to contribute (0.23.1 comes out on Friday), but if no one does, we should / can easily patch this for the next release.
