remove trailing / on meta tags (#856)

* remove trailing / on meta tags

Meta tags are [void elements](https://html.spec.whatwg.org/multipage/syntax.html#void-elements) which means they are self closing, and do not require a closing tag, nor a trailing `/`.

The trailing `/` is something that was required in XHTML but [is ignored
in HTML](https://html.spec.whatwg.org/multipage/syntax.html#start-tags). Quoth the spec:

> On void elements, [the trailing slash] does not mark the start tag as self-closing but instead is unnecessary and has no effect of any kind. For such void elements, it should be used only with caution — especially since, if directly preceded by an unquoted attribute value, it becomes part of the attribute value rather than being discarded by the parser.
