Evaluate System.Text.Json satisfies all mutation needs to be able to replace NewtonSoft.Json

System.Text.Json seems to have limited abilities in terms of writing/creating a JsonDocument. So we need migrate the runtime to use Newtonsoft.Json instead of System.Text.Json to achieve the relevant functionalities like creating JArray with elements etc.

Hi @mbhaskar , can you include a few references to project code or examples of where System.Text.Json is limited? I see a lot of docs that highly suggest migrating to System.Text.Json and would like to make sure we don't unnecessarily move to Newtonsoft. You mention 'JArray with elements,' and wondering what advantages you see there over JsonDocument.

As discussed over chat. We should first try the JsonNode API from System.Text.Json:
