2023-01-22 Pi-hole admin password changes - old-menu branch - PR 2 of 3

See SensorsIot#648 for background to this PR.

Consequential changes:

* harmonises template service definition by removing reference to port
443 but does not re-align other entries (did not seem worthwhile).
* harmonises default environment variables file so it is identical to
the inline environment variables on master branch. This includes
new-style TZ syntax and comments directing users to IOTstack wiki doco
on the admin password, and Pi-hole doco on supported environment
variables.
