Add Micro Configurations (#18)

* Begin changing files to recommendations rather than actual contents, that way multiple examples can be shown and when they are changed to be the real .yml they are not added to the project.

* Shrink the PHP limits more.

* Convert all configurations to be micro/standard.

* Double check the script supports IPv6. Shrink case statement.

* Fix uncommented nc-oo.

* Shrink NC further.

* Change name of env example.

* Change name of env example.

* Do not provide micro versions of DNS or PhotoPrism.

* Fix error in NC checks, wants at least 512M.

* Shrink more.

* Add a folder to keep static resources.

* Copy static resources into the container. This unfortunately doubles the size right now. Maybe do a volume in the future.

* Bring the description up to date.

* Make the description slightly more agnostic.

* Be more consistent about using variable.

+# This is a revised version of the original work here:

+
+# Changelog:
+#   2023-07-16
+#     Change from mariadb:10.5 to 10.6.
+#   2023-08-20
+#     Add Redis. (https://markontech.com/docker/setup-nextcloud-with-redis-using-docker/)
+#   2023-08-21
+#     Got NC to work with OO after specifying the Advanced parameters!
+#   2023-08-26
+#     Try combining OnlyOffice to here again. It has been on its own since
+#     2023-07-25 but isn't being used for anything else. OO is slow to respond
+#     and upgrades can no longer be done separately but this keeps it all easier
+#     to maintain and may allow the internal address to be based on container
+#     name instead of the docker hosts's IP.
+#   2024-01-23
+#     Experimenting with how small a Nextcloud installation can survive.
