Change page title on new broadcast template page

Since broadcast services can only have one type of template we probably
don’t need to disambiguate what kind of template you’re creating.

And you’ve just come from a page where the button says ‘New template’,
without the choice of radios after, so it’s nice for the page title to
match that.
