Fix #135999: Extensions: Remove emails in bl_info['author']

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.
