Fixing useradd feature documentation

The manages password and manages password age features of useradd were
inaccurately documented.

Support to manage passwords was added for 'useradd' in 0.22.4
Support to manage password ages was added for 'useradd'  in 2.6.2

This change retrofits all documents to reflect the appropriate features at the
time they were introduced

(#19006) Clarify the search order for templates

This patch updates the templating guide to be consistent with comments in the
Puppet codebase. When resolving a relative path to a template, Puppet will
first search relative to module paths and then fall back to searching relative
to the paths in `templatedir` if no matches are found.
(#19006) Link learning template chapter to guide

Add a cross-reference from the Templates chapter in Learning Puppet to the

(#19233) No variable interpolation for regex

Currently, the Datatype docs claim that:

> Regular expressions are written as standard Ruby regular expressions (valid
> for the version of Ruby being used by Puppet)

However a notable feature of forward-slash quoted Ruby regular expressions that
we do not support is variable interpolation.
