supporting: Update Newtonsoft.Json to 11.0.2, Newtonsoft.Json.Schema to 3.0.10

• Update supporting\validator\bin\Newtonsoft.Json to 11.0.2
  • HIGHLIGHT: support for regex operator in JSON Paths
  • Latest Newtonsoft.Json version is 12.0.1, which has some compatibility issues with Json.Schema 3.0.10 and PowerShell Core 6.1.12 (On my PC)
• Update supporting\validator\bin\Newtonsoft.Json.Schema to 3.0.10
• Use .NET 4.5 instead of .NET 4.0, since Scoop's requirements is .NET Framework 4.5+
• Modify json_path() to escape $version substitutions when $jsonpath has regex

EXAMPLE OF JPATH REGEX

"checkver": {
    "url": "https://dist.nuget.org/index.json",
    "jp": "$..versions[?(@.displayName =~ /.*recommended.*/)].version"
}

BTW, should supporting\shimexe\shim.csproj and supporting\validator\validator.csproj be deleted? build.ps1 is enough...

@r15ch13 Should this be merged or be closed and wait for your updating? Current ones are outdated for two years…
