GetExecutionResultForBlockID uses wrong query param #486

Problem

the access http.Client sets block_ids query param for GetExecutionResultForBlockID while the API spec uses block_id

This results in an error when calling the method with any block id

get execution results by IDs [df38d976b13ccfc40a379b1c779ee1ec2a4fb005b2dcb1bbc1ad823167cf8e3e] failed: no block IDs provided

Steps to Reproduce

resp, err := client.GetExecutionResultForBlockID(ctx, block.ID)
if err != nil {
	log.Fatal(err)
}
