Temporary alternative NuGet feed due to AV software false positives

[tuscen]

Due to our problems with ESET and other AV software that false positively mark our library as potentially unwanted temporarily we'll be publishing new packages to this feed: https://nuget.voids.site/v3/index.json.

We're waiting for a decision from the Nuget team how to proceed further.

The latest release there 20-alpha.6.stj supports Bot API 7.2 and is fully ported to use System.Text.Json instead of Newtonsoft.Json.

To use this feed you need to add nuget.config file to your project with the following content:

<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="TelegramBots Feed" value="https://nuget.voids.site/v3/index.json"  protocolVersion="3" />
  </packageSources>
</configuration>
