DeployCommerceDatabase: SQL Server Provider for Windows PowerShell is not installed.

After installing it, I can see that I now have the correct PowerShell module:

Note: If you get the same error, and have SQL Server 2017 installed instead of SQL Server 2016, have a look at this post from Marc Bastiaansen.
