Subject: [PATCH] =?UTF-8?q?Use=20=E2=80=9Cwww.youtube.com=E2=80=9D=20consi?=
 =?UTF-8?q?stently=20(#5768)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Saves an unnecessary redirect by using `www.youtube.com` on some parts of Invidious where `youtube.com` was used instead. youtube.com will redirect to www.youtube.com anyways.
