Wrong phpunit's junit.xml location in Drupal 10.2

Migrated issue

Reported by: el7cosmos

Related to !113 (merged)

Problem/Motivation

In Drupal 10.2, the location of phpunit's junit.xml will be under the web root directory instead of the project root. This makes it not uploaded as an artifact and not reported in the pipeline.

Steps to reproduce

Proposed resolution

Provide additional path for junit.xml in phpunit job.

Remaining tasks

- webroot or project directory?
