Schemas for "pruned" beacon blocks are incorrect

[ralexstokes]

Refer: https://github.com/ethereum/beacon-APIs/blob/master/apis/beacon/blocks/blinded_block.yaml#L34-L39

The schemas have "full" (signed) beacon blocks whereas this endpoint should provide blinded beacon blocks.

AIUI we should update these schemas to the right type -- and taking a look at the other blinded endpoints, I see a similar issue.

This issue appears fixed.

All blinded_* routes declare the blinded block types for post bellatrix and the full types for pre bellatrix. This is correct, since the pre bellatrix types do not have an execution payload thus full type = blinded type
