thinkfan.conf.5: rename complex -> detailed syntax

Hopefully, "detailed" is less off-putting to users than "complex", as
they should really be going for that instead of simple mode.

 This mode is suitable for more complex systems, with devices that have
 different temperature ratings.
 For example, many modern CPUs and GPUs can deal with temperatures above
 80\[char176]C on a daily basis, whereas a hard disk will die quickly if it
 reaches such temperatures.
