Added "remember me" feature in the login form

"Remember me" is a common functionality in login forms and I noticed that the demo application does not have it.

This PR is a small change and any user can easily find that in the documentation, but I believe that this is still a relevant addition in order to make this demo a bit more "complete" and show that Symfony can provide common functionalities out of the box.

I also didn't find any discussion (issue/pr) about this functionality so I don't know whether it was intended to not have it in the demo app.

What do you think?
