  <!--
    Nerdbank.GitVersioning appends GitBuildVersion/GitBuildVersionSimple/GitAssemblyInformationalVersion
    to $GITHUB_ENV whenever it runs under GitHub Actions (GITHUB_ACTIONS=true). When several projects or
    target frameworks build in parallel, those concurrent appends to the single $GITHUB_ENV file race and
    occasionally corrupt a line, which the runner then rejects with
    "Unable to process file command 'env' successfully. Invalid format '...'", failing the job.

    GITHUB_ACTIONS is a default environment variable that cannot be overridden from the workflow, so we
    stop the write at the MSBuild layer instead: nbgv's SetCloudBuildVersionVars target only runs when
    @(CloudBuildVersionVars) is non-empty, so we clear that item just before it. These CI variables are
    not consumed by this repository's build; the package/assembly versions are still computed from git.
