[rtpascual]

Changes

Add user groups and their precedence to amplify_outputs.json.

Example:

export const auth = defineAuth({
  loginWith: {
    email: true,
  },
  groups: ['Administrators', 'Editors']
});

{
  "auth": {
    ...
    "groups": {
      "Administrators": {
        "precedence": 0
      },
      "Editors": {
        "precedence": 1
      }
    }
  },
  ...
}
