feat: expose AppGate share link via APPGATE_LINK output

Capture the share_url returned by the release creation endpoint and
expose it as ENV['APPGATE_LINK'], lane_context[SharedValues::APPGATE_LINK],
and the action's return value, so later lane steps (e.g. Slack) can
reference the public download page. Warn when older servers omit it.
