Keep the app version in project.yml so XcodeGen can't reset it

project.yml declared `info: path: TopManager/Info.plist` without
properties, so every `xcodegen generate` rewrote Info.plist with
XcodeGen's defaults, 1.0 (1). That silently undid the version bump in
cf88044: its message says 1.1.1 (3), but the commit actually set
Info.plist back to 1.0 (1).

The version now lives in MARKETING_VERSION / CURRENT_PROJECT_VERSION in
project.yml, and the generated Info.plist references them. Regenerating
is idempotent and the built app reports 1.1.1 (3).
