docs(android): advertise the upcoming ScanditDesign library [SDC-33034]

[redwarp]

SDC-33034

8.6 introduces a new ScanditDesign library (com.scandit.datacapture:design) that ScanditCaptureCore depends on. Gradle and Maven consumers get it transitively from the published POM, but manual .aar integrations have to add ScanditDesign.aar themselves — otherwise resource linking fails, or DependencyChecker throws at SDK init. This PR gives those users advance warning while 8.5.x is still the current release.

What it does

A notice rendered under the breadcrumbs of the Android Installation and Release Notes pages — the two places a reader is deciding what goes into their build:

Coming in 8.6

The Scandit Data Capture SDK will require a new ScanditDesign library (com.scandit.datacapture:design), which provides the UI components used by the SDK's views.

Gradle and Maven integrations pull it in automatically; if you add the .aar files to your project directly, you will need to add ScanditDesign.aar yourself.

Preview

Follow-ups (not in this PR)

• Remove this component at the 8.6 cut, when 8.6: Declare ScanditDesign in the internal dependencies #388 lands the requirement in the internal-dependencies table. There is a note to that effect in the component's doc comment.
• 8.6 release notes still need an entry; suggested text for ### Behavioral Changes → #### Core:

  The SDK now requires the new ScanditDesign library (com.scandit.datacapture:design), which provides the UI components used by the SDK's views. Gradle and Maven integrations resolve it automatically as a dependency of ScanditCaptureCore; if you add .aar files to your project directly, you must also add ScanditDesign.aar.

• 8.6: Declare ScanditDesign in the internal dependencies #388 edits the shared _internal-deps.mdx, which iOS, Web, React Native, Flutter, Cordova, Capacitor and .NET pages all import — worth checking there, since the module is Android-only.
