Misleading CONTRIBUTING.md documentation

In the CONTRIBUTING.md file (in the examples namely) there are (probably obsolete) references to redshift / redshift-gtk there:

$ ./configure --prefix=$HOME/redshift/root \
   --with-systemduserunitdir=$HOME/.config/systemd/user
...
$ $HOME/redshift/root/bin/redshift-gtk # <=- mentioned redshift-gtk is not even built in the target directory ...

Another question is why is the root folder there? I've succesfully built it on recent debian-testing (bullseye/sid) for swaywm without the root folder.

My build configuration was (I used hard-typed paths as i built it as root):

./configure --prefix=/home/jirka/opt/gammastep/ --with-systemduserunitdir=/home/jirka/.config/systemd/user

Now it seems to work without problem (I have to wait till the dark to really confirm it).

In any case thank you very much for your work.
