BUG: fixed plotting of boolean dataframes

[BSchilperoort]

Boolean data was not recognised as plottable data. Adding it to the list of valid dtypes fixed this and allows plotting.

• closes Plotting boolean data fails #23719
• tests added / passed
• passes git diff upstream/master -u -- "*.py" | flake8 --diff
• whatsnew entry

Hello @BSchilperoort! Thanks for submitting the PR.

• There are no PEP8 issues in the file pandas/plotting/_core.py !

Needs tests and a release note.

I would probably include a new keyword include_bool for whether or not boolean data should be included. Currently, this will be a breaking change for people relying on boolean data being dropped. I don't have a strong opinion on what the long-term behavior should be, but for now we can make it False or None if we want to issue a warning and change it to True in the future.
