Add video content by Vue School to support written documentation. Links all refer to those previously discussed with Evan.

Here's what they look like in both light and dark mode:

Thanks!

There's currently a merge conflict.

Are these the exact same videos that were previously added to the old Vue 3 docs?

When you say 'previously discussed with Evan', do you mean in the context of the new docs? I seem to recall Evan mentioning reworking the video links in the new docs, but I'm unclear exactly what his plans were.

hey @skirtles-code my apologies on the merge conflict, I've now resolved that.
As far as discussing these links with Evan, these are not all the exact same links as before. In fact, many of them have been reproduced for better quality and cohesion with the new docs.

Evan and I corresponded on discord and in a notion doc to discuss link placements.

Thanks!

@skirtles-code to clarify my above comment @yyx990803 has approved the links in this PR via the notion doc. Thanks!
