Bump to 1.1 and read version from built app in CI

SideStore only shows an update when the version changes; the previous build
stayed at 1.0 so no update appeared. Bump MARKETING_VERSION to 1.1 and have
the workflow read CFBundleShortVersionString from the built app's Info.plist
instead of a hardcoded VERSION, so the metadata can never drift from the
pbxproj again.
