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
