Update .gitignore to exclude Docker's persistence directory

[Yannick243]

Docker's persistence folder (data) was not being ignored.

This is a small update to #1001

How are you running docker exactly? Are you running the sample yaml file directly in the docker directory perhaps?
Are you running this in production or development?

My bad, i was running it directly in the docker directory.

Hello @jonocodes;
I think this is this still relevant, as some people may run Docker directly from the Docker directory? Or am I mistaken?

I didnt think of that use case, but yeah it can be relevant since it may be a way people use it.
I am considering changing the name of the file to docker-compose.prodexample.yaml to make it a little more clear also.

So what is the next step?

I approved it. It can be merged.
