Because of how yarn install works, the progress bar removes the last line printed resulting in this output

➤ YN0000: ┌ Fetch step
➤ YN0000: ⠧ ===============================================================================-
Attempting to automatically open the SSO authorization page in your default browser.
If the browser does not open or you wish to use a different device to authorize this request, open the following URL:

https://maintainx.awsapps.com/start/#/device

Then enter the code:

➤ YN0000: ⠧ ===============================================================================-

So we add some newlines to ensure the code gets printed and the progress bar will instead remove one of the newlines
