Make beet.yaml video field optional

[runcows]

A majority of our modules have no video, so in the beet.yaml the field sits as null. This is easily forgotten, as has happened several times in new module PRs.

This PR makes the field optional as well as cleaning up existing video fields in all modules beet.yaml files.

• video: null fields have been removed. They would still work, I just figured I'd clean them up while I was here
• XP storages video link has been adjusted to no longer point to a playlist
• Particles Pack and Poses Pack each had their video link adjusted to no longer include a time argument

I believe that this was an intentional decision. Keeping video: null in all the beet.yaml files makes it clear where you can place the video link. I don't see any advantage in this tbh.

What is easily forgotten? Adding the field? It shouldn't be if you either copy bat grenades or follow the making-a-module docs.

This is intended. They are part of the better armour stands video.

Ah I totally missed that, woops. That change has been reverted

I'm still not convinced that we even need this at all, but it looks good in that this would work.

I disagree. The majority of our modules does not have videos, in fact, it has been years since we have made a module video. Videos are no longer the default, they are the exception. Hence having to put a boiler-plate video: null on every module even though they are never gonna get a video seems a bit silly.
