Have drupal-scaffold locations web-root for Varbase as docroot to fix composer web-root folder in projects

Problem/Motivation

Composer is fixed to docroot folder and should use web-root such as core composer to let use this project into custom folder.

Steps to reproduce

Having issues with custom composer build with Varbase profile conflicting with changes over Varbase Project template
When changed in projects, composer will face issues on builds and updates

Proposed resolution

1. Double-check what Drupal Recommended Project
https://github.com/drupal/recommended-project/blob/9.4.5/composer.json#L43
2. Check Acquia Drupal Recommended Project
https://github.com/acquia/drupal-recommended-project/blob/1.11.19/compos...

3. Use the right web-root in both Varbase profile and Varbase Project template

    "drupal-scaffold": {
      "allowed-packages": [
        "drupal/core",
        "vardot/varbase"
      ],
      "gitignore": true,
      "locations": {
        "web-root": "./docroot"
      },
      "file-mapping": {
        "[web-root]/sites/default/default.services.yml": {
          "mode": "replace",
          "overwrite": false,
          "path": "docroot/core/assets/scaffold/files/default.services.yml"
        },
        "[web-root]/sites/default/default.settings.php": {
          "mode": "replace",
          "overwrite": false,
          "path": "docroot/core/assets/scaffold/files/default.settings.php"
        },
        "[web-root]/robots.txt": {
          "append": "docroot/profiles/varbase/src/assets/varbase-robots-additions.txt"
        }
      }
    },

Projects could change "web-root": "docroot/" and docroot to web using change or a clone of the Varbase Project Template
