Navigation: HTML ul element should not contain aria-expanded

[alexstine]

On profiles.wordpress.org and possibly other sites, the ul element has aria-expanded.

<nav id="site-navigation" class="main-navigation" role="navigation">
					<button class="menu-toggle dashicons dashicons-arrow-down-alt2" aria-controls="primary-menu" aria-expanded="false" aria-label="Primary Menu"></button>
					<div id="primary-menu" class="menu">
						<ul class="nav-menu" aria-expanded="false">
													<li class=""><a href="https://login.wordpress.org/register?locale=en_US&amp;redirect_to=https%3A%2F%2Fprofiles.wordpress.org%2Falexstine%2F" rel="nofollow">Register</a></li>
							<li><a href="https://login.wordpress.org/?redirect_to=https%3A%2F%2Fprofiles.wordpress.org%2Falexstine%2F&amp;locale=en_US" rel="nofollow">Log In</a></li>
						
						</ul>
					</div>
				</nav>

The ul element should not have aria-expanded only a trigger button.

Looks like this is coming from ​https://profiles.wordpress.org/wp-content/themes/profiles.wordpress.org/navigation.js?ver=1

Thanks @alexstine!

It looks like this was taken care of for the rest of the themes in [7964] via #3927, this copy of that JS file was missed.

Fixed via r18793-dotorg.

Profiles: Remove unnecessary aria attribute.
