Replace 5XX to actual errors

[paunin]

Some Swagger generting clients treat status code as integer and hence unexpect to see 5XX as string. Example here

Think it's even safe to skip those errors in the annotations

# subStatus is something that changes too often on Fireblocks Side - so we just make it string
yq eval-all '(select(fileIndex == 0)
  | del(.components.schemas.TransactionResponse.properties.subStatus.$ref)
  | del(.paths.*.*.responses.5XX)
  | .style="double"
) *+ select(fileIndex == 1)' fireblocks-api.yml fireblocks-api-additions.yml > fireblocks-result.yml

Thats's the patch we do to make client work BTW
