Steam group exclusive always set to 1 in entry script

https://github.com/Left4DevOps/l4d2-docker/blob/e573a1fdfa0b1bef99b17d64c7cbf73aede53557/entrypoint.sh#L43C1-L45C11

This section will always set steam group exclusive to 1 even if the env variable is set to 0 because it only checks for the existence of the variable, not the value.

I have "- STEAM_GROUP_EXCLUSIVE=0" in my compose file and the server launches with +sv_steamgroup_exclusive 1"

You can omit to disable, but I should fix the expression. Setting to false should disable but isn't working here.

It looks like LAN suffers from the same problem. I think you should update the entry script to perform safety check for valid variable before passing them to the command line.

That would make it more feasible to update the readme to contain a complete compose file making it easier for anyone to setup a server.

You can use mine and add it to the readme to help setup a server faster and easier.
