Add a user config for using git's external diff command for paging

Browse Source 
This is similar to using lazygit's Git.Paging.ExternalDiffCommand config, except
that the command is configured in git. This can be done either with git's
`diff.external` config, or through .gitattributes, so it gives a bit more
flexibility.
