Use the type in yorkie-sdk-js

Description:
Use the type provided by yorkie-js-sdk

Why:
we can code by knowing the parts provided by yorkie-js-sdk better.

I'm interested in this issue, and it seems to be using the type definitions defined from yorkie-js-sdk module just fine.

but I still don't understand what needs to be changed. 🤔 👀

Previously, the methods provided in the SDK did not match the methods we were actually using.

Currently, the provided methods are matched all what we use
https://yorkie.dev/yorkie-js-sdk/yorkie-js-sdk.jsonarray.html

so I think it is better to use a combination of generics and sdk methods without defining types in codepair anymore.
