Temporarily exclude DigitalOcean artifact caching proxy provider

[lemeurherve]

As infra.withArtifactCachingProxy accepts a boolean since jenkins-infra/pipeline-library#615, this PR excludes the DigitalOcean ACP provider while working on jenkins-infra/helpdesk#3481
The AWS provider isn't concerned by the issue and is working as intended.

Replayed the build so I could have one with my modifications, it's not using the ACP when running from a DigitalOcean agent, LGTM.

(I've stopped the build as there is no need to waste resources on a full build to check this modification)
