Migrate query requests to v2

[andresmgot]

At the moment, we are using v1 for doing request in ADX but using v2 is recommended.

Relevant links:

• API overview: https://learn.microsoft.com/en-us/azure/data-explorer/kusto/api/rest/request
• Query v2 response format: https://learn.microsoft.com/en-us/azure/data-explorer/kusto/api/rest/response2

We need to check if there is any breaking change we need to be aware of.
