Rename the DDEV config.yml to config.yaml

[vodde]

Describe the bug

The .ddev folder contains a config.yml file with some default settings.
However, DDEV actually (now) looks for a file called config.yaml ( notice .yml vs .yaml ).

Running ddev config and going through the configuration does end up creating a config.yaml file, but that results in 2 almost similar named configuration files, which can cause confusion as the single letter difference is easy to miss.

Include some logs

N/A

Reproducing

1. Download the template, and unzip it in a folder
2. run ddev start in the folder
3. The error message Failed to start project(s) .. appears, specifying that .ddev/config.yaml was not found

Expected behavior

After running ddev start, the project should spin up without any error messages.

Your environment

Windows OS with WSL2 ( integrated Docker, not Docker Desktop )

As far as I know, DDEV never supported config.yml.

let's go ahead and resolve #14 then this won't be an issue.
