Run automated tests on sauceLabs platform

[ikallala]

I want to run automated tests on specific browser version but tests were always executed with last browser version.
I added the config below in serenity.properties

saucelabs.url =sauceUrl
saucelabs.driver.version=83
saucelabs.target.platform=Windows 10
webdriver.driver = chrome

it used to work but now the execution is allways using the last version (same for other browsers)
Note: It works well with selenium
