Deprecation notice - Dependabot will no longer support Composer v1

[jonjanego]

As of November 6, 2024, Dependabot will no longer support Composer version 1, which has reached its end-of-life. If you continue to use Composer version 1, there's a risk that Dependabot will not create pull requests to update dependencies. If this affects you, we recommend updating to a supported release of Composer. As of October 2024, the newest supported release of Composer is 2.8, and the long-term supported version is 2.2.
