Update link in HTTPS warning
When you visit Foris on HTTP, you will see each time HTTPS warning (flash warning to be more precise), but the link in that warning redirects you to the community documentation. This fixes it to use our official documentation, which is for now only in English.
On router you can find it in: /usr/lib/python3.7/site-packages/foris/templates/index.html.j2
But to apply changes in that file, you need to restart lighttpd. This can be done by this command: /usr/bin/maintain-lighttpd-restart
Tested and works.
