Clicking component tab resets anchor to top of page

[GCHQ-Developer-741]

Summary

When you click on a tab on a component page, because technically a new page loads, the page jumps back to the top. If you scroll down half way and then click a tab, it would be good to see the tab content change instead of a new page thus taking you back to the top.

💰 Use value

Would make navigation of the website flow more easily and be less jarring.

Would want page Header to stay in the same location, but not the content of the "fake" tab

Worth making sure this does not flash for usability reasons
