Change of overrides.extends behavior

We changed the overrides.extends behavior to merge rather than replace, to make it consistent with the overrides.plugins.

If you would like to keep the previous behavior, you should change your config to:

{
- "extends": ["config-a"],
  "overrides": [
    {
      "rules": ["*.module.css"],
      "extends": ["config-b"]
    },
+   {
+     "rules": ["*.css"],
+     "extends": ["config-a"]
+   }
  ]
}
