fix(ui): Handle Email dropdown in alert creator for Safari (#33741)

Safari is disregarding autocomplete='off' and still showing the browser autocomplete for the select action field in the alerts creator. This is due to the first/default option being set as Email, so having an invisible character to break up the word seems to fix this. Seems to be an open issue with react-select and the other solutions mentioned here don't work for Safari JedWatson/react-select#3500.
