fix: improve our docker config (#1373)

* greatly simplify docker

* back to gcc since I can't the libs to load properly

* fix typo
add set -e to entrypoint
better copy of entrypoint.sh and use proper entrypoint

* use debian instead of gcc for runtime
comment and organize it a bit
drop gcc to 12 since we are using debian 12 as well

* explicitly include mariadb libs

* Make the server not crash in the case we are using only env-vars
make the dockerfile have configs in the expected location incase of bypassing entrypoint.sh

* remove unneede var from example, since it's in the container now

* coments to dockerfile

* Revert master server changes

* Resolve conflicting port options between chat, master, and world
move chat_server_port to shared since it's used by world and chat

* Don't error if file does not exists when updating a config option
move update before and use bin dir var

+# Docker
+
+## Standalone
+
+For standalone deployment, you can use the image provided via Github's Container Repository:
+`ghcr.io/darkflameuniverse/darkflameserver`
+
+This assumes that you have a database deployed to your host or in another docker container.
+
+A basic deployment of this contianer would look like:
+```sh
+# example docker contianer deployment
+docker run -it \
+    -v /path/to/configs/:/app/configs \
+    -v /path/to/logs/:/app/logs \
+    -v /path/to/dumps/:/app/dumps \
+    -v /path/to/res:/app/res:ro \
+    -v /path/to/resServer:/app/resServer \
+    -e DUMP_FOLDER=/app/dumps \
+    -p 1001:1001/udp \
+    -p 2005:2005/udp \
+    -p 3000-3300:3000-3300/udp \
+ghcr.io/darkflameuniverse/darkflameserver:latest
+```
+You will need to replace the `/path/to/`'s to reflect the paths on your host.
+
+Any config option in the `.ini`'s can be overridden with environmental variables: Ex: `log_to_console=1` from `shared_config.ini` would be overidden like  `-e LOG_TO_CONSOLE=0`
+
+## Compose
+
+See the [compose](docker-compose.yml) file in the root of the repo.
+
+This compose file is for a full deployment: MariaDB, DarkflameServer, and Nexus Dashboard.
+
+All of the environmental options are listed in the compose file so the can be pass through, or you can edit the compose file to suit your specific needs
