Documentation for other platforms than macOS

[mahal]

Description

At the moment, all documentation on audiokit.io is referencing to macOS. Example: https://www.audiokit.io/AudioKitUI/documentation/audiokitui/adsrview inherits from AppKit.NSView

Proposed Solution

It would be helpful to either choose platform or mark availability on each class / struct.

Describe Alternatives You've Considered

I've tried to build the documentation with docc for iOS, which would be in my case a bit more helpful than macOS but swift-docc-plugin doesn't support choosing the platform:
apple/swift-docc-plugin#38

I've considered other means of generating the documentation as described in https://danielsaidi.com/blog/2022/04/27/building-multi-platform-documentation-with-docc

It looks a bit overwhelming to migrate to xcodebuild docbuild or to implement something new and integrate it into the existing CI flow

Additional Context

As a workaround: Add a .docc to each framework, build documentation manually in Xcode, export it and create a PR here.
