WIP: home: delta: use stand-alone configuration file
All checks were successful
ci/woodpecker/push/check Pipeline was successful
Details

Browse source 
Ideally, I'd like for `delta` to just read a configuration file at
`$XDG_CONFIG_HOME/delta/config` by default, but upstream seems somewhat
reticent to the idea :-/.

TODO:
* `git.enable = false` would break the standalone configuration
* using a wrapper which sets `--config` might be better than includes
