Testing

I tested this using the following steps:

1. git clone https://github.com/palantirnet/drupal-skeleton.git
2. cd drupal-skeleton
3. composer install
4. cd vendor/palantirnet && rm -rf the-build
5. git clone https://github.com/palantirnet/the-build.git
6. cd the-build
7. git checkout --track origin/TECH-33-update-phpcs-xml-during-the-build-install
8. ddev start
9. ddev ssh
10. vendor/bin/the-build-installer
11. When prompted, specify pantheon as the hosting platform.
12. Once the install is complete, ensure that phpcs.xml has the following lines:

  <!-- Directories to scan. -->
  <file>web/modules/custom</file>
  <file>web/themes/custom</file>

13. Repeat steps 1-10
14. When prompted, specify acquia as the hosting platform.
15. Once the install is complete, ensure that phpcs.xml has the following lines:

  <!-- Directories to scan. -->
  <file>docroot/modules/custom</file>
  <file>docroot/themes/custom</file>

I don't think I adequately described what we need here. We actually need to modify the contents of:
https://github.com/palantirnet/the-build/blob/develop/defaults/install/phpcs.xml

Specifically, we need to change these lines in the file when the web root is changed from docroot to web:

the-build/defaults/install/phpcs.xml

Lines 32 to 33 in fc7b0ff

	<file>docroot/modules/custom</file>
	<file>docroot/themes/custom</file>

The file should always be copied to the project root.

See the following example:
https://github.com/palantirnet/the-build/blob/develop/targets/install.xml#L164-L173

In the above example, we are updating the installer-paths in composer.json whenever we change the web root. See:
https://github.com/palantirnet/drupal-skeleton/blob/develop/composer.json#L82-L91
