CI: failure in delete-workload-cluster (bin/env: No such file or directory)

There are failures in delete-workload-cluster, but not always.

Here is one: https://gitlab.com/sylva-projects/sylva-core/-/jobs/14893053041

/bin/bash: line 698: /builds/sylva-projects/sylva-core/bin/env: No such file or directory

This is on an MR targetting main, on a capo run.

This is very similar to #4100 (closed)
