* Fix resource links
Fixes#12839
Some video links still refer to the outdated "/teleport/" path.
This change adds the videos these links refer to to the "img"
directory and updates the links.
Note that two of the three MDX files that are changed here do not
actually render the video. I've changed the links here anyway in
case someone uses these as a reference for the link format.
