Repository meta-issue: Linter configuration re: void elements

[ferdnyc]

In my latest PR, I noticed that the [mdn-linter] is "correcting" tags like <img ...> to <img ... />. It... really shouldn't.

The standard, on the use of trailing / characters in (void element) start tags:

Then, if the element is one of the void elements, or if the element is a foreign element, then there may be a single U+002F SOLIDUS character (/), which on foreign elements marks the start tag as self-closing. On void elements, it 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.
