Bug: translate="no" is minified incorrectly

[coliff]

Hi. I think I found a bug. With Hugo 0.78.2 and minify HTML option enabled (default minification settings), it minifies the following:

<h1 translate="no">Navigation</h1>

to:

<h1 translate>Navigation</h1>

which doesn't work as expected. Translate="no" is a HTML5 attribute and is used on the new Safari to tell the browser not to auto-translate a particular div/span etc. - useful for product/brand names etc.

I hope this could be fixed so that it'd be minified to:

<h1 translate=no>Navigation</h1>

Thanks! This should be fixed, please let me know if you still run into trouble.
