• The right tests are in and and the right validation has happened. Guidance: https://github.com/dotnet/core-eng/tree/master/Documentation/Validation

There aren't any automated validations set up here, but pasting this (exactly what I changed) into a local project file and running it shows it does what i want:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="Build">
  <Target Name="Build">

    <PropertyGroup>
      <ScmRepositoryUrl>https://devdiv.visualstudio.com/DevDiv/_git/DotNet-msbuild-Trusted</ScmRepositoryUrl>
      <_TranslateUrlPattern>(https://dnceng%40dev\.azure\.com/dnceng/internal/_git|https://dev\.azure\.com/dnceng/internal/_git|https://dnceng\.visualstudio\.com/internal/_git|dnceng%40vs-ssh\.visualstudio\.com:v3/dnceng/internal|git%40ssh\.dev\.azure\.com:v3/dnceng/internal|https://devdiv\.visualstudio\.com/devdiv/_git)/([^/-]+)-(.+)</_TranslateUrlPattern>
      <_TranslateUrlReplacement>https://github.com/$2/$3</_TranslateUrlReplacement>
    </PropertyGroup>

    <Message Importance="High" Text="Untranslated URL : $(ScmRepositoryUrl)" />

    <PropertyGroup>
      <ScmRepositoryUrl Condition="$(ScmRepositoryUrl.Contains(`devdiv.visualstudio`))">$(ScmRepositoryUrl.ToLower().Replace(`-trusted`,``))</ScmRepositoryUrl>
      <ScmRepositoryUrl>$([System.Text.RegularExpressions.Regex]::Replace($(ScmRepositoryUrl), $(_TranslateUrlPattern), $(_TranslateUrlReplacement)))</ScmRepositoryUrl>
    </PropertyGroup>

    <Message Importance="High" Text="Translated URL : $(ScmRepositoryUrl)" />

  </Target>
</Project>
