Pipeline broken

[imbachb]

This pipeline as it is here seems to be broken.

I cloned this repository and tried to run it in an Azure Devops project.

When running it the pipeline throws the following error:

##[warning]An image label with the label Ubuntu 16.04 does not exist.
,##[error]The remote provider was unable to process the request.
Pool: [Azure Pipelines](https://opiniongames.visualstudio.com/31c0df6c-eb00-46d6-b29d-f13c4feb61eb/_settings/agentqueues?poolId=&queueId=155)
Image: Ubuntu 16.04

When I set ubuntu-latest as the vmImage I get following warnings in the Use PHP version 7.2 step:

Finishing: Use PHP version 7.2

It does not use the configured PHP version 7.2 but the default installed one, which is currently PHP 8.1.11.
This seems to be a very recent change, as ubuntu-latest has been working for me up until end of last week (17.11.2022).
Through trial and error I found that Ubuntu 18.04 has php7.2, but then the pipeline fails in the composer install step.
