Problem/Motivation
Initially filed details in the wrong place: #3478331-26: Upgrade composer to 2.8.1 for PHP 8.4 - the errors look like:
Drupal\BuildTests\Composer\Template\ComposerProjectTemplatesTest::testTemplateCreateProject with data set "recommended-project" ('drupal/recommended-project', 'composer/Template/RecommendedProject', '/web')
COMMAND: COMPOSER_HOME=/tmp/build_workspace_558dd1b0a4860999e23c68f3b3390b60dlYMeC/composer-home COMPOSER_ROOT_VERSION=11.0.6 composer create-project --no-ansi drupal/recommended-project test_project 11.0.6 -vvv --repository /tmp/build_workspace_558dd1b0a4860999e23c68f3b3390b60dlYMeC/test_repository/packages.json
OUTPUT:
ERROR: Running 2.8.1 (2024-10-04 11:31:01) with PHP 8.3.10 on Linux / 6.8.0-40-generic

Tests actually started to break in ci pipelines because the image was updated. @andypost filed #3479441: Upgrade composer to 2.8.2 for PHP 8.3 for that.
Steps to reproduce
Run \Drupal\BuildTests\Composer\Template\ComposerProjectTemplatesTest::testTemplateCreateProject with composer 2.8.1 installed / in the $PATH.
Proposed resolution
