STEPS TO REPRODUCE

1. Create a new project with a reference to a package that
   a. has a minor or patch upgrade
   b. specifies a version range, e.g.
   <PackageReference Include="Microsoft.AspNetCore.Authentication.Negotiate" Version="[6.0.13,7)" />
2. Run the upgrade command, e.g. dotnet-outdated --version-lock Major --upgrade

EXPECTED RESULT

The specified version range is preserved, i.e. the resulting reference should be
<PackageReference Include="Microsoft.AspNetCore.Authentication.Negotiate" Version="[6.0.14,7)" />

ACTUAL RESULT

Version ranges are removed, i.e. the resulting reference is
<PackageReference Include="Microsoft.AspNetCore.Authentication.Negotiate" Version="6.0.14" />
