📝(self-hosted) Add step to copy default.conf.template when using nginx-proxy

[jco-c]

Purpose

When self-hosting docs, my reverse proxy configuration didn't work as I didn't copy default.conf.template to my docs directory. To prevent this issue for future installations, I want to add a step to the compose docs to copy the default.conf.template file.

This is my first pull request for this project, so please let me know if I did something wrong in this process :)

Proposal

• Add a step to copy the default.conf.template file to the docs directory

I also added a commit to make the commands copy-pastable by adding the folder-name (e.g. docs, keycloak, etc.) to the curl command. Otherwise I would have to change the directory before executing the curl commands. Please let me know if I should remove that commit :)
