Hello,
We are updating composer in the CI images from 2.1.8 to 2.3.3 which
update most jobs relying on PHP.
The "Quibble" jobs have not been upgraded due to prerequisites tasks
that have not been completed yet.
If you find something suspiciously related to the composer upgrade,
please report on the upgrade task or as a subtask:

Thank you!
