Blueprint ignores error_format option

[Stuart]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

add_route and its route-decorator friends respect the error_format option to specify "text", "json", or "html", as documented here.
But if I wrap the route in a blueprint, the error_format option no longer works, it just uses the default.

Code snippet

Without Blueprint

from sanic import Sanic
import sanic.exceptions

app = Sanic("MyHelloWorldApp")

@app.get("/", error_format="json")
async def hello_world(request):
    raise sanic.exceptions.SanicException("Big Mistake, Huge.", status_code=400)

// Elsewhere...

$ curl localhost:8000/ -i
HTTP/1.1 400 Bad Request
content-length: 73
connection: keep-alive
content-type: application/json

{"description":"Bad Request","status":400,"message":"Big Mistake, Huge."}

With Blueprint

from sanic import Sanic
import sanic.exceptions

app = Sanic("MyHelloWorldApp")

bp = sanic.Blueprint("MyBlueprint")

@bp.get("/", error_format="json")
async def hello_world(request):
    raise sanic.exceptions.SanicException("Big Mistake, Huge.", status_code=400)

app.blueprint(bp)

// Elsewhere...

$ curl localhost:8000/ -i
HTTP/1.1 400 Bad Request
content-length: 68
connection: keep-alive
content-type: text/plain; charset=utf-8

⚠️ 400 — Bad Request
====================
Big Mistake, Huge.

Expected Behavior

I expect the error_format option to be applied to the blueprint route the same as if applied to an app route.
