chore(sidebars): sync sidebars in v8.5/3.13.0

[pepopowitz]

Description

Synchronizes sidebars for v8.5/3.13.0.

• There is only one meaningful change in the main instance's version-8.5-sidebars.json file, and a bunch of whitespace changes.
• There are a handful of meaningful changes in the Optimize instance's version-3.13.0-sidebars.json file.

When should this change go live?

• This is a bug fix, security concern, or something that needs urgent release support.
• This is already available but undocumented and should be released within a week.
• This on a specific schedule and the assignee will coordinate a release with the DevEx team. I'd like to merge these sidebar sync PRs by the end of this week.
• This is part of a scheduled alpha or minor. (apply alpha or minor label)
• There is no urgency with this change and can be released at any time.
