Change Newtonsoft to System.Text.Json

[Phalanx123]

Possibly change Newtonsoft usage to System.Text.Json to reduce reliance on third-party libraries?

Will look into it. Thanks.

I'd avoid this if you're doing anything more than using Newtonsoft to deserialize. System.Text.Json only support reading Json at this time. For consistency sake I would stick with Newtonsoft until System.Text.Json catches up.

Microsoft is constantly improving System.Text.Json and there has been significant improvements between .Net Core 3.1 and .Net 5.0 and Microsoft has already started planning for .Net 6.0.
With the info above in mind, I'm planning to do the migration in the new release of Airtable.net.

Interested in this due to DateOnly and TimeOnly.

Newtonsoft.Json.JsonSerializationException: Error converting value to type System.DateOnly

Replaced Newtonsoft.json with System.Text.Json 6.0.2.

FYI: I tried to upgrade from 1.1.5 to 1.3 but the result does not work because my enum values can't be converted properly by System.Text.Json because this library does not use the EnumMember attribute. See dotnet/runtime#74385 for more details.

I will therefore have to stay with 1.1.5 because of this change of dependency in the AirTable nuget 😢
