AUTO: Docs repo sync - ScalarDL

[github-actions]

Warning

Don't merge this PR until we're ready to add Scalar Kubernetes and Helm Charts docs in Japanese to this docs site.

This is an automated pull request (PR) to sync changes to ScalarDL docs in the centralized private docs repo to this public docs site repo.

Before merging this PR, confirm the following:

• I have updated the side navigation to include new docs or remove deleted docs (if necessary).
• I have confirmed that this PR can be merged without waiting (if necessary).
  • An example of when a PR must wait to be merged is when the docs are part of a pending release of a new product version.

Closing this PR since #88 contains more up-to-date docs.
