initdb: nothing about template0

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/14/app-initdb.html
Description:

Is it correct that this page does not contain information about the
template0 database.
The same goes for the "Create Database Cluster" page
(https://www.postgresql.org/docs/14/creating-cluster.html).

Maybe it makes sense to add that template0 is also created when the database
cluster is initialized?
