x/website: Make search box remember what you typed

[mleonhard]

What did you do?

1. Go to https://golang.org/
2. Click the three-bars icon to display the menu.
3. Click in the Search box.
4. Type sha 256 and hit ENTER.
5. See the empty result page.
6. Click the three-bars icon to show the menu again.
7. Click in the Search box.
8. Type sha-256 and hit ENTER.
9. See the empty result page.
10. Click the three-bars icon to show the menu again.
11. Click in the Search box.
12. Type sha256 and hit ENTER.
13. See some useful results.

What did you expect to see?

I expected that the text I entered in the Search box would remain. Then I could refine my search by editing the text.

What did you see instead?

The Search box was cleared after each query. I had to type the text again to refine my search.
