BUG: Adds newline after info() call on empty dataframe

[EzraBrauner]

• closes BUG: missing newline when info is called on DataFrame #45494
• tests added / passed
• Ensure all linting tests pass, see here for how to run them
• whatsnew entry

This fix improves the formatting of the output of pd.DataFrame.info() when called on an empty DataFrame by adding a newline, per the above issue.

I don't know if this is the proper style for adding newlines, but it appears to pass the linting tests. I'm pretty new to open-source development so let me know if anything should be changed.

Thanks - please add a test too

[MarcoGorelli]

actually, perhaps you could modify

pandas/pandas/tests/io/formats/test_info.py

Line 31 in cac2245

def test_info_empty():

instead of adding a new test?

Will also need a whatsnew note
