Provide license Url in NuGet

This would help in automated OSS scans.

We used to have it (have a look at older versions). Unfortunately it is now deprecated. https://github.com/NuGet/Announcements/issues/32

This is in fact the generated nuspec:

<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2013/05/nuspec.xsd">
  <metadata>
    <id>CacheCow.Server</id>
    <version>2.6.3</version>
    <authors>Ali Kheyrollahi</authors>
    <owners>Ali Kheyrollahi</owners>
    <requireLicenseAcceptance>false</requireLicenseAcceptance>
    <license type="expression">MIT</license>
    <licenseUrl>https://licenses.nuget.org/MIT</licenseUrl>
    <projectUrl>https://github.com/aliostad/CacheCow/</projectUrl>
    <description>CacheCow is an HTTP Caching Library for .NET</description>
    <dependencies>
      <group targetFramework=".NETFramework4.5.2">
        <dependency id="CacheCow.Common" version="2.6.3" exclude="Build,Analyzers" />
        <dependency id="Microsoft.AspNet.WebApi.Client" version="5.2.5" exclude="Build,Analyzers" />
        <dependency id="Microsoft.AspNet.WebApi.Core" version="5.2.5" exclude="Build,Analyzers" />
        <dependency id="Newtonsoft.Json" version="11.0.1" exclude="Build,Analyzers" />
      </group>
      <group targetFramework=".NETStandard2.0">
        <dependency id="CacheCow.Common" version="2.6.3" exclude="Build,Analyzers" />
        <dependency id="Microsoft.AspNet.WebApi.Client" version="5.2.5" exclude="Build,Analyzers" />
        <dependency id="Microsoft.AspNetCore.Mvc" version="2.0.3" exclude="Build,Analyzers" />
        <dependency id="Newtonsoft.Json" version="11.0.1" exclude="Build,Analyzers" />
      </group>
    </dependencies>
  </metadata>
</package>

It has license now hence you should still be able to automate - I would argue much easier now.

Indeed, we have an OSS scan running and for some reason it did not detect the license in the nuspec. We need to look at our tool. Thanks for your nice implementation!
