Adds the Holy Skateboard, a holy version of the hoverboard. (#84514)

## About The Pull Request
This is my first PR ever, and I have tested it. It just adds an
additional nullrod variant that could be helpful for people that wish to
explore space as a chaplain, or chaplains that wish to look sick and
tubular.
## Why It's Good For The Game
More nullrods are better. Also, it's a fun vehicle that i feel allows
for more gimmicks as the 540 cr cost for a regular hoverboard is a bit
steep. It's not super good, and it's not bad, so I feel it doesn't
affect balance too much.
## Changelog
🆑
add: There's a previously undiscovered variant of a nullrod, recently
revealed from the depths of the skating rink..
