DOC: DataFrame.plot is missing most of the docstring
In the pandas 0.25.0 docs, at
[pandas.DataFrame.plot.html](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.plot.html)

#### Problem description

The page is essentially missing. The only content is 

```
DataFrame.plot(self, *args, **kwargs)[source]
Call self as a function.
```

#### Expected Output

It should look like [0.23.4 DataFrame.plot.html](https://pandas.pydata.org/pandas-docs/version/0.23.4/generated/pandas.DataFrame.plot.html)
