Add a notice about the port to access Kibana.

This is an updated version of #7303. I'm sorry I had not noticed about the last comments by the reviewer. I rebased the commit, changed its insertion point, and changed the text to the suggested one.

Can one of the admins verify this patch?

@jgbarah Thanks for resubmitting! I have a suggestion for new phrasing after the first sentence:

Now you can point your web browser to https://localhost:5601 and start using Kibana! When running npm start, Kibana will also log that it is listening on port 5603 due to the base path proxy, but you should still access Kibana on port 5601.

Thanks for the quick review. I just amended the commit with the sentence you suggested.

Another thing (sorry if I missed this in the previous review): I think this paragraph should go after the "> On Windows, ..." paragraph, and it should not include a > so it appears as normal text. So it would look like this:

This way the "on windows" thing is still explaining a needs for running the previous command, whereas the new text is simply explaining what's next.

I understand, and I agree this is better. New version committed.
