DOC: Wrong spaces in the documentation

[datapythonista]

In #23738 we fixed many cases where a space was missing before the colon splitting the parameter name and the type (e.g. name: str changed to name : str).

But in few cases spaces were added in places where they were not required or wrong, for example:

• In directives: .. deprecated :: 0.21.0
• In rst lists: Series : the user provides a pandas.Series object of the same
• In code: "border" : {"top": "thin",

We should restore those cases and remove the added spaces.

I'll take a stab at this. We want to remove all of the spaces before colons if it is not a parameter?

should I use commit f247355 to see what parts of the documentation were refactored and adjust non parameter documentation?

That's right, use better https://github.com/pandas-dev/pandas/pull/23738/files to see what was fixed, and remove the spaces in the examples shown in the description, and equivalent cases.

e.g. .. deprecated :: 0.21.0 -> .. deprecated:: 0.21.0

Excellent! I'll get on this tonight..

@datapythonista thank you for the direction.
