Add more method variations for setting the `error` codec on `Endpoint`

[987Nabil]

The method outError is missing a way to set a media type and there is no convenient way to set error to a custom value

[ffprivacy]

outError media type response should be the one requested by the client (Accept headers). #3284 should close this issue.

For the custom error message, the following works:

   case class BookNotFound(message: String, bookId: Int)
    object BookNotFound {
        implicit val schema: Schema[BookNotFound] = DeriveSchema.gen
    }
    case class Book(title: String, authors: List[String] = List.empty)
    object Book {
        implicit val schema = DeriveSchema.gen[Book]
    }
    var books = List(
        Book("Harry Potter", List("JK Rolling"))
    )
    val bookEndpoint =
    Endpoint(
        RoutePattern.GET / "books" / string("bookname").examples(("example1", "Harry Potter")) 
        ?? Doc.p("Route for querying books")
    )
        .out[List[Book]]
        .outError[BookNotFound](Status.NotFound)

    routes = routes :+ bookEndpoint.implement {
        case (booknameEncoded) => {
            val bookname = net.URLDecoder.decode(booknameEncoded, StandardCharsets.UTF_8.toString)
            println(f"${bookname} ${books(0).title}")
            val booksFiltered = books.filter(_.title == bookname)
            if ( booksFiltered.isEmpty ) {
                println(f"bookname=${bookname} not found")
                ZIO.fail(BookNotFound(f"Book ${bookname} not found", 0))
            } else {
                ZIO.succeed(booksFiltered)
            }
        }
    }
    endpoints = endpoints :+ bookEndpoint
