Update references for System.Text.Json

[albgen]

Describe the bug
The latest version of Restsharp is referencing the version 8.0.0.4 of System.Text.Json which is Vulnerable
This means that i can't update the System.Text.Json because it will break the dependency.

To Reproduce
Use Restsharp latest version and also reference to latest version of System.Text.Json.

Expected behavior
Load the latest assembly of System.Text.Json
