DOC: description for Series.empty is referencing DataFrames instead of Series
#### Location of the documentation

https://pandas.pydata.org/docs/dev/reference/series.html
https://pandas.pydata.org/docs/dev/reference/api/pandas.Series.empty.html

#### Documentation problem

The description about Series.empty are referencing DataFrames instead of Series:

https://pandas.pydata.org/docs/dev/reference/series.html

> Series.empty | Indicator whether DataFrame is empty.

https://pandas.pydata.org/docs/dev/reference/api/pandas.Series.empty.html

> True if DataFrame is entirely empty (no items), meaning any of the axes are of length 0.

(And many more references to "DataFrame" instead of "Series" on that page.)

#### Suggested fix for documentation

Replace all mentions of "DataFrame" with "Series".
