    List 'setEnv' as opposite of 'getEnv'
    
    It seems best to direct users to use 'System.Environment.setEnv'
    rather than 'System.Posix.Env.putEnv'. This is due to 'setEnv' being
    located in the same module as 'getEnv' and my virtue of working on
    Windows platform, whereas 'putEnv' does not have that quality because
    it's part of the 'unix' package.
    
    (cherry picked from commit c74fcf5d27744c67b09b29a78029c31c9371cf41)
