Fix the skip-to-content link reloading the results

Fixes

Fixes #3940 by @sarayourfriend

Description

This PR converts the skip-to-content link to an a anchor link instead of using the VLink component because this component links to a hash #content URL, and VLink introduces unnecessary complexity for it.
To stop the media re-loading when clicking on skip-to-content, I added a check for hash in the search.ts middleware. We don't update anything in the middleware if the navigation was caused by a hash change.

Testing Instructions

Try searching for something, and then use Tab to focus the Skip-to-content button, click on the button to navigate to content. You should not see the media reload or the content links change number of results.

Excellent! There is one thing that is broken but it is a one line fix, so I will pre-approve knowing you will add the fix so we can get this critical bug resolved and unblock deployments.

This works as expected locally! I don't see the results reload when using the button.
