ProductVersion of pwsh.exe lists Git commit ID twice

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

The ProductVersion string in the version resource of almost every PowerShell PE file lists the same Git commit ID twice, separated with a plus sign. Just once would be enough.

(However, that does not apply to Microsoft.PowerShell.MarkdownRender.dll, where the ProductVersion is just 7.2.1.)

Expected behavior

PS> (Get-Item "${PSHOME}/pwsh.exe").VersionInfo.ProductVersion
7.6.0 SHA: 6effea0e216b190f989e227f5a20b670804a07fb
PS> (Get-Item "${PSHOME}/pwsh.dll").VersionInfo.ProductVersion
7.6.0 SHA: 6effea0e216b190f989e227f5a20b670804a07fb
PS> (Get-Item "${PSHOME}/System.Management.Automation.dll").VersionInfo.ProductVersion
7.6.0 SHA: 6effea0e216b190f989e227f5a20b670804a07fb
PS> Get-Item "${PSHOME}/*.dll","${PSHOME}/*.exe" | Where-Object { $_.VersionInfo.ProductName -like '*PowerShell*' } | Group-Object { $_.VersionInfo.ProductName},{ $_.VersionInfo.ProductVersion } | Select-Object Count,Name

Visuals

No response

The issue names pwsh.exe, pwsh.dll, and System.Management.Automation.dll but no source file or test; start by tracing the build or version-resource entry point that produces their ProductVersion values. Reproduce with the shown Get-Item commands and consider the work done when PowerShell binaries report the commit ID once while Microsoft.PowerShell.MarkdownRender.dll remains unchanged.
