Fix Swagger apidocs validation errors

[kkaris]

When running the example for indra_subnetwork_relations, there is an error that looks like the payload is badly formatted. The given example is correct, but the swagger docs seems to do some format checking and doesn't allow the example to be sent because of this.

The complaint is that indexes 0 and 1 in the list must be strings, although currently they are lists of strings. Fixing it to comply with the swagger error allows the request to be sent but yields an error on the backend instead (since now the payload is not properly formatted for it):

The backend errors with this:

ERROR: [2024-09-11 19:28:10] indra_cogex.apps.queries_web - norm_id() takes 2 positional arguments but 8 were given
ERROR: [2024-09-11 19:28:10] indra_cogex.apps.wsgi - Exception on /api/indra_subnetwork_relations [POST]
Traceback (most recent call last):

TypeError: norm_id() takes 2 positional arguments but 8 were given

I see two solutions worth exploring:

1. Turn off validation if possible. I quickly tried locally to pass validate=False and format_checker=None to Flask restx's Api() class, but it didn't seem to make a difference, I might have been missing something.
2. Fix potential source of issue: it looks like the code generating the endpoints assume that all parameters are just lists of strings (coming from parameters being tuples of (namespace, identifier), see queries_web/__init__.py, line 116. In the case above, the parameters is a list of lists (list of tuples in the python code). The fix here would be to make sure the correct flask_restx.fields type is used for the endpoint, perhaps by adding them next to the examples for the parameters.

I quickly tried option 2 and it seems to work.
