fix: typespec of result

[yordis]

Context

We had an issue today because we forgot to pattern match on {:error, code, body}

%CaseClauseError{
  term: {:error, 400, %{
    "message" => "filters: Unexpected token string(Card) expected ‘)’ at col 22", "status" => 400
  }}
}

This also matches:

algolia-elixir/README.md

Line 35 in 3dcfa2c

- `{:error, error_code, response}`

I fixed the issue, but

file.ex:107:pattern_match
The pattern can never match the type.

Pattern:
{:error, __status, _body}

Type:
{:error, _}
