Please change the default baseURL

Please change this to something like `https://example.org/`. In the Hugo forums we get large number of new users that get in to trouble because they keep this example setting.

Open exampleSite/config.toml at the referenced first line and inspect the current baseURL setting. Change it to an example.org URL, then verify that the example site configuration uses the requested default and that no other change is needed.
