[Version History] Collision with MiniApp Manifest version field

[alancutter]

Potential issue for the version history explainer: https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/VersionHistory/explainer.md

The MiniApp Manifest is an extension to the web app manifest, and it already defines a version member: https://www.w3.org/TR/miniapp-manifest/#version-member

Not sure what exactly should be done about this but FYI regardless.
