Revise `.editorconfig` and `.globalconfig` documentation

The page mentions the following:

> If you have an existing .editorconfig file for editor settings such as indent size or whether to trim trailing whitespace, you can place your code analysis configuration options in the same file.

But is this the best way to go? I think a better advice is to have both `.editorconfig` and `.globalconfig` files with editor settings in `.editorconfig` and analyzer configuration options in `.globalconfig`.

cc @sharwell @mavasani thoughts?
