Previously when an addon is expanded on the UI, the "Maintainer" string would be cut short until a `<` character, to prevent showing e-mail on the UI, however there could be more than one person/email entries in there so to prevent cutting short the string, now we use regex to take out the email part only, so full maintainer string is displayed.
