Remove the git.paging.useConfig option

Many people don't understand what this means, which is apparent from the amount
of issues that got filed because of this. Let's get rid of it to avoid this
confusion. People will have to configure their pager twice if they want to use
it both on the command line and in lazygit, which I think is not a big deal.

 the `colorArg` key is for whether you want the `--color=always` arg in your `git diff` command. Some pagers want it set to `always`, others want it set to `never`.

 Be careful with this one, I think the homebrew and pip versions are behind master. I needed to directly download the ydiff script to get the no-pager functionality working.

 ## Using external diff commands
 
 Some diff tools can't work as a simple pager like the ones above do, because they need access to the entire diff, so just post-processing git's diff is not enough for them. The most notable example is probably [difftastic](https://difftastic.wilfred.me.uk).
