fix(docker): Fix support for docker list manifests

[danez]

Changes:

Add a missing n.

Context:

I guess the tests work as they are both (test+code) using this constant, but the actual runs don't work and fail with:

DEBUG: Invalid manifest - returning (repository=INFRASTRUCTURE/security-checker-job)
"manifest": {
"manifests": [
{
"digest": "sha256:3747d4eb5e7f0825d54c8e80452f1e245e24bd715972c919d189a62da97af2ae",
"mediaType": "application/vnd.docker.distribution.manifest.v2+json",
"platform": {"architecture": "amd64", "os": "linux"},
"size": 528
},
...
],
"mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",
"schemaVersion": 2
}
