ERROR: The AnalyzerReleases.Shipped.md $token token replacement failed.
The 'nbgv' tool is required but not installed.

To recover manually:

1. Install the nbgv tool (see the docs/make-release.md documentation)
2. Run: nbgv get-version -v MajorMinorVersion
3. In $file, replace the $token token with the version returned from step 2
4. Run: git add $file && git commit --amend --no-edit
5. Run: nbgv get-version -v MajorMinorVersion again to ensure the version is the same as step 2 before proceeding
