docs(ngHref): close the <a> tags in examples

Self closing <a> tags in the examples given make no sense because they won't
show up in the browser (and I think aren't even allowed according to HTML specs).
I've seen this confuse people over at stackoverflow.com who tried to copy/paste
those examples.

Closes #8488
docs(guide/controller): remove duplicate -Controller suffix

Closes #8482
docs(guide/concepts): add min to numerical inputs
