fix: ddev init-full-automated-testing skips the testing users (add-testing-users not on the container PATH)

Problem/Motivation

On the Varbase Project Template 10.1.x (Drupal ~11.4), running ddev init-full-automated-testing to bootstrap the Varbase functional testing suite (webship-js: Playwright + Cucumber-js) never creates any of the per-role testing users.

Root cause: inside the DDEV web container, sibling ddev web commands are not on PATH. The script calls the users-provisioning script as a bare command, add-testing-users, instead of by path. That resolves to nothing (which add-testing-users → not found), and the call is guarded with || true, so it fails silently. None of the per-role testing users (Editor/Content admin/SEO admin/Site admin/Super admin) are ever created, so the Varbase functional testing suite — which logs in as those roles — cannot run.

Steps to reproduce

1. ddev start
2. ddev drush sql:drop -y
3. ddev init-full-automated-testing
4. No testing users exist after init.

Proposed resolution

• .ddev/commands/web/init-full-automated-testing: call the users-provisioning script by its absolute container path instead of a bare command name, e.g. bash "/var/www/html/.ddev/commands/web/add-testing-users" || true, so it actually resolves and runs.

Related: an earlier version of this issue also reported init-full-automated-testing aborting on a non-fatal oEmbed fetch during drush site:install. That was root-caused to the dead Vimeo demo video shipped by varbase_media_demo, and has been fixed and released separately in varbase_media_demo 10.1.1 (issues #3608459 and #3609161). With that fix released, the init script needs no oEmbed handling — set -e fail-fast is correct as-is — so it is intentionally not part of this issue.
