In the PowerShell 7.5 documentation on manipulating Environment Variables, it suggests that you can clear an environment variable by setting it to an empty string or $null in at least these sections:

• Use the variable syntax
• Use the System.Environment methods
• Set environment variables with SetEnvironmentVariable()

As noted in PowerShell/PowerShell#21186 (comment), PowerShell 7.5 introduced the ability to set environment variables to an empty string instead of unsetting the variable.

It would be wonderful if the documentation could reflect this new enhancement!
