"pipenv activate" doesn't recognize PowerShell on Windows

[doxxx]

Issue description

When I execute py -m pipenv activate in a PowerShell 7 shell on Windows 11, it doesn't recognize the shell. But running py -m pipenv shell successfully launches a PowerShell sub-shell.

Expected result

The activation commands for PowerShell to be printed to the console.

Actual result

❯ py -m pipenv activate
unknown shell C:\Program Files\PowerShell\7\pwsh.exe

Steps to replicate

1. Install PowerShell Core 7 on Windows 11.
2. Install Python 3.x using Python Install Manager.
3. Using PowerShell Core 7, in a new directory, execute py -m pipenv install serial to create the Pipfile etc.
4. Using PowerShell Core 7, in the same directory, execute py -m pipenv activate to display the activation commands.
