Cannot import collection in Postman and cannot start Northport example

[zeldalegends]

Hi,
I have noticed two main issues:

• All *postman_collection.json cannot be imported in Postman ("Error while importing : format not recognized"), neither uploading the file nor pasting it as raw content. The version of Postman used is:

Postman for Web
Version 9.25.3-220722-0800
Chrome 103 / Windows 10

• Northport cannot be tested. Steps to reproduce the error:

Not all of the security tutorials have been fully ported over to NGSI-LD yet. This NGSI-LD tutorial is incomplete and has not been added to ngsi-ld-tutorials.readthedocs.io yet. The principles of securing FIWARE are orthogonal to the version used, so for the moment you should use the NGSI-v2 PEP-Proxy tutorial which is the master branch.

cycle found: tutorial -> iot-agent -> iot-agent has now been fixed 24d32cf but other parts of the tutorial are still incomplete
