Specify image tag 1.1.1 in docker-compose.yml for php and apache images.

[#5] Revert "Merge branch 'issue-4' into 'main'"

Closes #5

See merge request !4

This reverts merge request !2

Specify image tag 1.1 in docker-compose.yml for php and apache images.

[#3] Fix HTTP 403 (Forbidden) errors

Closes #3

See merge request !3

Currently, the Apache server attempts to use port 9000 on the php
container for handling PHP files and loads all other files from
/var/www/html - however, /var/www/html does not exist in the Apache
container.  This results in the error: Forbidden - You don't have
permission to access this resource.

The web files from the php container should be shared with the apache
container, mounted at /var/www/html. A volume called www-data will now
be mounted on the php container and then mounted on the apache container
at /var/www/html. This allows both the containers to access these files.

[#4] Upgrade to PHP 8.0

Closes #4

See merge request !2

Currently, the php container uses the php:7.4-fpm-alpine Docker image as
its base. This was initially due to Multicraft's lack of support for PHP
8.0. Multicraft now fully supports PHP 8.0 so the php:8.0-fpm-alpine
image will now be used as the base.

[#2] Fix error Jinja variable 'str object' has no attribute 'host'

Closes #2

See merge request !1

Attempting to deploy php/application.php.dist in Salt results in the
following error: Unable to manage file: Jinja variable 'str object' has
no attribute 'host'.

This was caused by the php/application.php.dist expecting the Multicraft
SMTP information to be available though pillars.  This file has been
updated to instead use the vault.read_secret module to get the data from
Vault directly.

Specify image tag 1.0 in docker-compose.yml when pulling down php and
apache images.

Create a simple Dockerised Multicraft project which will build Docker
images with the Multicraft panel configured as required for MinersRealm.

The supplied .gitlab-ci.yml will build the images when pushed to main.
These images are then used by the supplied docker-compose.yml file which
pulls them down and mounts the application config.

Create an empty PhpStorm project with a .gitignore file generated by the
.ignore plugin to ignore JetBrains files.
