Updated Connectable and BlockRotateV2 to 1.21

[Miniontoby]

Updated connectable.ts to work again for 1.21

Will require people to add the scripts/connectable.js to their main.js file in order to work!
I don't know how to make that super clear to them

---

And updated BlockRotationV2 to work in 1.21
This one doesn't require scripting.

Thank you for your contribution. I'll verify and hopefully merge it this weekend.

At least to show that it works on my end, here's a screenshot:

The blue lines have the Connectable and the RTC thing has the BlockRotateV2 (of course only one of the tags, but they are all updated, so go test them out, I don't know how I would test such thing)

I was thinking about how to communicate to the user that main needs to be used. I think the best we can do is include the information in the plugin readme, then if a user is specifically confused and asks in the discord we point them to the answer.

Sounds good, not too sure if the readme is correct since you would just have your main in the scripts folder anyways

and then just add import './connectable.js' is good enough, but its fine
