When using strawberry.file_uploads.Upload with asgi, it seems that no type checking at all is performed on the input.

Describe the Bug

Test server:

import strawberry
from strawberry.asgi import GraphQL
from strawberry.file_uploads import Upload

@strawberry.type
class Query:
    @strawberry.field
    def upload(self, file: Upload) -> str:
        return "success"

schema = strawberry.Schema(query=Query)
application = GraphQL(schema)

Start server with uvicorn server:application

The following commands all return "success":

curl "http://127.0.0.1:8000" -F operations='{ "query": "query($file: Upload!){ upload(file: $file) }", "variables": { "file": null } }' -F map='{ "file": ["variables.file"] }' -F file="@testfile"

=> expected

curl "http://127.0.0.1:8000" -F operations='{ "query": "query($file: Upload!){ upload(file: [$file]) }", "variables": { "file": null } }' -F map='{ "file": ["variables.file"] }' -F file="@testfile"

=> this is a list?

curl "http://127.0.0.1:8000" -F operations='{ "query": "query{ upload(file: 1) }" }'

=> ??
