Wikimedia CI recently switched to Composer version 2.5.1. (T319257), however mwcli is still on version 2.1.8
It would be great if mwcli could follow what is running on CI, so that we can anticipate and reproduce CI issues related to docker also locally.
As I understand it, the file that governs the relevant docker image is https://gitlab.wikimedia.org/repos/releng/cli/-/blob/f8b0171a089e80f7b38974b7a11556d7affc3023/internal/mwdd/files/embed/mediawiki.yml
And if I read that file correctly, then the image in question is docker-registry.wikimedia.org/dev/buster-php74-fpm
