[docs] [issue22997] Minor improvements to "Functional API" section of Enum documentation

[Simeon Visser]

New submission from Simeon Visser:

This patch contributes two changes to the "Functional API" section of the Enum documentation:

- Early in the section it mentions four different ways of creating an Enum but later it only lists three different ways (the "sequence of names" approach wasn't listed anymore).

- The use of "Animal" and "Animals" wasn't consistent.

This issue is mainly to test my ability to make a (trivial) patch.
