ci: fix swag ci failure caused by typo annotation

Previous version:

type SignedBlock struct {
	BlockID   uint64         `json:"blockID"`
	BlockHash string         `json:"blockHash"`
	Signature string         `json:"signature"`
	Prover    common.Address `json:"proverAddress"`
}

// GetSignedBlocks handles a query to retrieve the most recent signed blocks from the database.
//
//	@Summary		Get signed blocks
//	@ID			   	get-signed-blocks
//	@Accept			json
//	@Produce		json
//	@Success		200	{object} []SignedBlocks
//	@Router			/signedBlocks [get]

SignedBlocks -> SignedBlock.
SignedBlocks structure can not be detected as object so the ci failed like this:
