appium: Appium Server uiautomator2 server apk v.1.9.1 does not exist

The problem

Running appium on Android is not currently possible after recent release of appium uiautomator2 server https://github.com/appium/appium-uiautomator2-server/releases. Now when trying to run Android tests on CI, the following issue occurs:

An unknown server-side error occurred while processing the command. Original error: /usr/local/lib/node_modules/appium/node_modules/appium-uiautomator2-server/apks/appium-uiautomator2-server-v1.9.1.apk file doesn't exist. (Selenium::WebDriver::Error::UnknownError)
