Cluster diagram labels docs that are in queue as not received

[ajeanmahoney]

On the Clusters page, the list for C535 correctly shows the following:

RFC 9679: draft-ietf-cose-key-thumbprint - published
draft-ietf-suit-manifest - in queue
draft-ietf-suit-firmware-encryption - in queue
draft-ietf-suit-mti - in queue
draft-ietf-suit-report - in queue
draft-ietf-suit-trust-domains - in queue
draft-ietf-suit-update-management - not received
draft-ietf-suit-mud - in queue

The diagram on https://purple.staging.ietf.org/clusters/535/ has labeled the following correctly:

draft-ietf-suit-update-management - not received
draft-ietf-suit-manifest - in queue
draft-ietf-suit-mud - in queue

However, the diagram also shows that the following are not received, but they are all in the queue:

draft-ietf-suit-firmware-encryption
draft-ietf-suit-mti
draft-ietf-suit-report
draft-ietf-suit-trust-domains

backend payload looks good, seems to be issue when plotting the graph
