Specify correct repo and path for "Edit this page" link on docs

I noticed the "Edit this page" link was broken on the docs site and did a bit of investigation to figure out the fix.

Assuming I'm correct and the docs site uses doks-child-theme, [this example `params.toml` file](https://github.com/h-enk/doks-child-theme/blob/master/config/_default/params.toml) suggests the use of the parameter I've added in this PR.

Hope this is correct!
