Kam 4d24f465e3 fix(docs-infra): load cross-origin video embeds under COEP credentialless ...

adev is cross-origin isolated (COOP same-origin + COEP require-corp) so the
embedded WebContainer editor can use SharedArrayBuffer. Under require-corp the
cross-origin YouTube iframe in `<docs-video>` only loaded in Chromium, leaving
the player blank in Safari.

Switch COEP from `require-corp` to `credentialless`. The page stays cross-origin
isolated, so the editor keeps working, but cross-origin frames are now allowed
to load, which restores the inline player in Safari as well.

(cherry picked from commit 86cd166141)
