Show output while updating EasyEngine

While updating EasyEngine, we don't see any output of what EasyEngine is doing in the update. We get output as following:

# ee cli update

You have version 4.0.9. Would you like to update to 4.0.10? [y/n] Y
Downloading from https://github.com/EasyEngine/easyengine/releases/download/v4.0.10/easyengine.phar...

Updating EasyEngine to new version. This might take some time.
New version works. Proceeding to replace.
Success: Updated EE to 4.0.10.

However many times it takes too long to update and the user does not know what's happening creating a feeling of uncertainity. Hence we need to show the output of update while updating.
