Description

I am trying to upgrade a project built with SPFx 1.12.1 to 1.13.0-beta.13. It errors out with the message:
Error: CLI for Microsoft 365 doesn't support upgrading projects build on SharePoint Framework v1.12.1

Steps to reproduce

1. Install the latest CLI: beta (v3.9.0-beta.8c84ab1)
   npm i -g @pnp/cli-microsoft365@next
2. run the upgrade command on SPFx 1.12.1 project:
   m365 spfx project upgrade --preview --shell powershell

Expected result

Instructions on how to upgrade to 1.13.0 beta.

Actual result

Error: CLI for Microsoft 365 doesn't support upgrading projects build on SharePoint Framework v1.12.1

Note: the same CLI allowed me to successfully upgrade projects built on SPFx 1.12.0.

Environment

Windows 10
Nodejs 14.16.1
SPFx 1.12.1 Web Part
CLI v3.9.0-beta.8c84ab1
