AUTO: Docs repo sync - ScalarDL (#749)

* AUTO: Sync ScalarDL docs in English to docs site repo

* Delete README.mdx

* Delete sdks.mdx

* Remove SDK section and SDK doc

The Java Client SDK doc doesn't provide much value and the contents have recently been referenced in other docs, so it  along with the SDK section can be removed for now.

 A simple way to store data in an asset is to always store the latest state of the data in its entirety. However, this approach is sometimes inefficient from a storage cost perspective because, if a small part of the data is updated frequently, almost all the parts of the data are stored as duplicates in the asset records.
 
-In such a case, you can choose to put only the differential data when updating the asset and merge all the asset records when you want to get the whole image of the latest data. Although this approach is efficient from a storage cost perspective, it affects query performance since it requires scanning all asset records. To limit the affects of this trade-off, creating a snapshot at some point in time is also an option so that you do not have to scan all asset records every time. [The generic contracts for collection authenticity management](./use-generic-contracts.mdx#manage-collection-authenticity) follow this design pattern.

 As explained above, what you need to do to create your contracts is to extend the predefined base contract classes and override the `invoke` method as you like. For details, see [A Guide on How to Write a Good Contract](how-to-write-contract.mdx).

-You have two options to interact with ScalarDL: using [commands](scalardl-command-reference.mdx) as shown in the [getting started guide](getting-started.mdx) or using the [Java Client SDK](scalardl-java-client-sdk/README.mdx).

 Using commands is convenient because you don't need to write applications. However, they invoke a process for each execution, which is slow, so they are mainly for quickly testing your contracts. Instead, using the Client SDK is usually recommended when you write ScalarDL-based applications because it is more efficient.
 
 The Client SDK is available on [Maven Central](https://search.maven.org/search?q=a:scalardl-java-client-sdk). You can install it in your application by using a build tool such as Gradle. For example in Gradle, you can add the following dependency to `build.gradle`, replacing `VERSION` with the version of ScalarDL that you want to use.

 #### Benefits of Asset Proof
 
-Since Asset Proof is evidence at the time of execution by Ledger, it is difficult for Ledger to tamper data after the evidence is created because the proofs and Ledger states would be diverged. Thus, making use of Asset Proof appropriately could reduce the risk of data tampering.
