[nnsnodnb]

• Update GitHub Actions' steps version.
• Update query and syntax in passkey/views.py.

I think there is a risk that Passkey ID on database will be leaked.
If you are checking user matches, I think it would be a good idea to retrieve it as a query and set it as Not Found.

id is reserved as a built-in function.

$ python
>>> id
<built-in function id>

if q.count()==1:  # a query
    key=q[0]  # a query
    # follow code...

This code generates the query twice.
Also, here we only have one matching data, so we can improve it by using first().

django.http.response provides HttpResponseForbidden and the status is set to 403.
