    GitCommitCountForInnerBuild
    GitCommitCountForRestoreGraph
    GitCommitCountForProjectReference

    Minimize git command execution by passing GitCommitCount to inner builds.
    For repos with a large history, consider setting GitCommitCount as an environment variable
    before building the project(s), e.g. in Powershell: $env:GitCommitCount = git rev-list −−count HEAD

    UpdateVersion

    Updates $(Version), $(PackageVersion), and $(FileVersion) with $(GitCommitCount)
    for all major build targets (Restore, Build, Pack).

    $(Version)        - If it contains any -/+ label, $(GitCommitCount) is appended.
                        If it is only Major.Minor.Patch, it will remain unchanged
                        and adding the SourceRevisionID to $(InformationalVersion)
                        will be supressed.
    $(PackageVersion) - If undefined or equal $(Version), set to updated $(Version).
    $(FileVersion)    - If undefined, set to Major.Minor.Patch of $(Version).
                        If less than four parts, $(GitCommitCount) is ALWAYS appended.
