Docs request: "default" config

[jamesbraza]

pylint provides an examples module that has several example configs (pylintrc, pyproject.toml). I use these to speed up adding new config options (and it promotes awareness of the available config options).

A huge benefit of this is also revealing the default behavior of all config options.

I think it would be cool if toml-sort had something similar. Fwiw, https://github.com/pappasam/toml-sort/tree/b9b6210da457c38122995e434b314f4c4a4a923e#configuration-file has an example config, but it doesn't document if it's the "default" config.

Proposal

The request here is to add example config(s) somewhere to docs/
