Remove 'value' attribute from an '<a>' tag
Remove 'value' attribute from an '<a>' tag

I initially thought this was missing a ``{% trans %}`` tag but according to [MDN](https://developer.mozilla.org/en/docs/Web/HTML/Element/a) ``value`` isn't a valid attribute to put on an ``<a>`` tag anyway so this commit removes it.
