Segment Containers: Transcript does not match video

Issue in ./help/components/segmentation/segment-containers.md: the transcript is for a different video than the one on the page. The transcript begins with "Hi. I’m Ben Gaines," while the video on the page begins with "Hey everybody, this is Doug."

Open ./help/components/segmentation/segment-containers.md and compare its transcript with the video currently shown on the page. Confirm which video is embedded and replace or update the transcript so it matches that video; done means the opening speaker and the rest of the transcript correspond to the displayed video.
