[UserWarning] Use instance.ctx._spec instead

[comic31]

Hello 🖖,

Since the last version, a warning is shown upon starting sanic.

UserWarning: Setting variables on Blueprint instances is deprecated and will be removed in version 21.9. You should change your Blueprint instance to use instance.ctx._spec instead.

from sanic import Sanic
from sanic.response import json
from sanic_openapi import swagger_blueprint

app = Sanic(name="sanic_openapi_test")
app.blueprint(swagger_blueprint)

@app.route("/")
async def test(request):
    return json({"hello": "world"})

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)

• OS: Ubuntu
• sanic-openapi==21.3.1 | sanic>=21.3.0

I created a pull request that fixes this warning

Thanks,

[artcg]

🔥 (thanks for the fix)
