docs(animation): update link to motion one

[dwightjack]

In the animation page, we link to a deprecated version of Motion One for Vue. The new implementation is Oku Motion and is still based on Motion One.

This PR fixes the link and refactors the related paragraph. I am not sure how to update the Stackblitz demo, but the only changes needed are:

1. Switch the packages:

npm remove motion
npm install @oku-ui/motion --save

2. replace motion/vue with @oku-ui/motion in App.vue

Thanks for the PR @dwightjack ! Can you help update the Stackblitz demo too by forking demo? And make sure everything in demo still works? 😁

@zernonia Sure. I pushed a commit with the forked demo.

Noticed there's some warning after changing to Oku Motion. Seems like not affecting the animation. Perhaps we should logged issue or maybe adapt to the changes? 😁

[dwightjack]

I didn't notice them! It seems there is an open issue on Oku Motion about those warnings: oku-ui/motion#36.

Do you think we should wait until the issue gets fixed (these changes aren't a high priority)?

[zernonia]

Yeah I suggest let's wait a see 😁
