When we use `:method:`, only the function name will show up. So, this will read a bit better like this I think:

    The :class:`Symfony\\Component\\Stopwatch\StopwatchEvent` object can be retrieved from 
    the :method:`Symfony\\Component\\Stopwatch\\Stopwatch::start`, 
    :method:`Symfony\\Component\\Stopwatch\\Stopwatch::stop`,
    :method:`Symfony\\Component\\Stopwatch\\Stopwatch::lap` and
    :method:`Symfony\\Component\\Stopwatch\\Stopwatch::getEvent` methods.

Also, can you add line breaks so that we have a line break after the first word that crosses the 72nd character? With these long `:method:` things, we often will put those entirely on their own line.

We usually also add a `versionadded:: 2.5` tag above a feature that is new, but I'm not sure here - it seems like a lot of work just for the 1 new method `getEvent`. Let's see what others think.

Thanks!
