In the current CI test job, PHP extensions are installed through the ppa:ondrej/php repository. Although a very useful repository, it is not suitable for this purpose, as the installed extensions are possibly incompatible with the installed PHP version due to using different source code versions.
Note: alternatively, the entire call could be removed, since both extensions are part of the base cimg/php image already. However, this may cause breakage in the future if the list of default extensions of this image is altered.
Describe your change

What problem is this fixing?
In the current CI test job, PHP extensions are installed through the
ppa:ondrej/phprepository. Although a very useful repository, it is not suitable for this purpose, as the installed extensions are possibly incompatible with the installed PHP version due to using different source code versions.My assumption is that this currently goes undetected as the call currently causes an entire second PHP version to be installed, see e.g. https://app.circleci.com/pipelines/github/algolia/scout-extended/255/workflows/ec6dc973-ce16-4d43-82e8-a61c2b2b4cd4/jobs/2079/parallel-runs/0/steps/0-104.
Note: alternatively, the entire call could be removed, since both extensions are part of the base
cimg/phpimage already. However, this may cause breakage in the future if the list of default extensions of this image is altered.
