pyplot.annotate() API deprecation #15142

Bug report

Bug summary

I wanted to update my code that annotates a plot by changed the deprecated keyword argument s to text as described in the documentation of matplotlib v3.1.1. However it fails to recognise text as an argument and requests s instead.

Code for reproduction

import matplotlib
import matplotlib.pyplot as plt


print(matplotlib.__version__)
print(matplotlib.get_backend())
matplotlib.pyplot.plot()
matplotlib.pyplot.annotate('without keyword', xy=(0.5, 0.75))
matplotlib.pyplot.annotate(s='keyword "s"', xy=(0.5, 0.5))
matplotlib.pyplot.annotate(text='keyword "test"', xy=(0.5, 0.25))

Actual outcome

3.1.1
TkAgg
Traceback (most recent call last):
  File "<input>", line 9, in <module>
TypeError: annotate() missing 1 required positional argument: 's'

Expected outcome

I would expect that the keyword we should use in version 3.1.1 would be 'text' since in the documentation (https://matplotlib.org/3.1.1/api/_as_gen/matplotlib.pyplot.annotate.html) it says:

Matplotlib version

• Operating system: Windows
• Matplotlib version: 3.1.1
• Matplotlib backend (print(matplotlib.get_backend())): TkAgg
• Python version: 3.7.4

I installed matplotlib through pip
