DOC: fix the incorrect doc style in 1.2.1

[jreback]

@jorisvandenbossche pls following up and fix the docs

it's not a style issue rather this is completely inconsistent with the current docs

we NEVER use the style - always ipython docs style

I moved this to the 1.2.2 milestone, there is no need to have this block the release IMO (and 1.2.2 is targetted for a few weeks anyway, which will then still update the docs for this).

Now, about the actual issue:

• About >>> vs In [] ipython style in the code-blcocks: we actually do use this style in the docs, see eg in the 1.0.0 release notes: https://pandas.pydata.org/docs/dev/whatsnew/v1.0.0.html#dataframe-rename-now-only-accepts-one-positional-argument. We can of course still discuss that we would like to make this more consistent, but so it is not that this is "never" used
• About code-blocks vs executed ipython directive: I of course needed some code-blocks for the behaviour that will change, therefore I prefer to use plain code blocks for the full example to have consistent look within that subsection (ipython directives and code blocks (even with ipython style In[]) look slightly different)

then pls fix those - that is incorrect

pls don't change what we do everywhere else

we are very consistent about using ipython and not code blocks in new code - this is done deliberately

if you want to make a style change then propose it rather than unilaterally changing
