Change prefect.docker import to prefect.utilities.dockerutils

[neumann-nico]

Change deprecated prefect.docker import to new prefect.utilities.dockerutils import.
Previous import lead to a bug that crashed when trying to import custom blocks based on the S3Block.
This only happens with the latest prefect 2.10.11 update. More information can be found in the issue.

This might require a bump of the minimum prefect version?
