HTML writer: improve alt-text/caption handling for HTML5 
Screen readers read an image's `alt` attribute and the figure caption,
both of which come from the same source in pandoc. The figure caption is
hidden from screen readers with the `aria-hidden` attribute. This
improves accessibility.

For HTML4, where `aria-hidden` is not allowed, pandoc still uses an
empty `alt` attribute to avoid duplicate contents.

Closes: #6491

The same text is already in the <figcaption> and
screen-readers would read it twice, see #4737
