feat: update version object

Add touchpanelWrapperApp, userInterfaces, and repoUrl to VersionData config schema

VersionData/NugetVersion previously only modeled the essentials and
packages entries under the versions node. This adds support for the
touchpanelWrapperApp (single object) and userInterfaces (array) nodes,
plus a repoUrl property on NugetVersion so it round-trips instead of
being silently dropped, matching the schema produced by the
vsce-essentials-version-manager extension.
