Update example in readme.

[oxinabox]

The current example has a few problems

1. It is for GoCD, which noone in julia community uses (I was at time created this investigating using it but decided not to)
2. It shows pass (info lost), even though we now have that info
3. It is missing a lot of the extra fields we added over the last few years, like time and timestamp and hostname

It would be good to update this.

@omus are you able to provide an example and screenshot from the new tool you are using this with?

We're using a tool called Ketryx for assisting with managing software compliance. Ketryx can use JUnit XML reports as an input for test case results but doesn't really have a nice output for showing the JUnit XML. From what I've seen either I end up viewing XML snippets or the raw XML file itself.
