add --rm to docker run line

[Habbie]

Proposed changes

Add --rm to the example docker run hello-world calls in the docs.

This would avoid leaving a (stopped) container lying around, as can be seen in docker ps -a.

I believe that, if you agree, multiple pages would want this change. Let me know and I'll push more commits (and I'm happy to squash afterwards).

I don't think this change is necessary. hello-world is very small, a few KB in size (excluding Windows).

I don't think this change is necessary. hello-world is very small, a few KB in size (excluding Windows).

It is 13.3kB on my system. run --rm does not recover those, and that was not the point of the PR. I trust a user will prune at some point and recover that space - which also does not seem important. I like my ps -a to cover things I wanted to have running.

For what it's worth, I like the PR. The hello-world container is a simple test and only has temporary use; therefore it should leave no trace after it's done.
