fix: resolve env path in case windows redirects installation path

[finswimmer]

Applications installed from the Microsoft Store are not allowed to write directly into %Appdata%, instead any attempt to do this is redirected to a sandbox folder located at C:\Users\username\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0.

Fortunately when one try to access this place during runtime, the Path object is a symlink that can be resolved and than be passed to the subprocess call that creates the venv.

Is there any way other than manual that we can test it?

I'm not aware of any other way. In an ideal world there would be an image for the github checks with windows and python installed from the store.

Tested on a Windows partition, and installation works flawlessly for both 1.2.0b2 and 1.1.13:

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

C:\Users\<REDACTED>\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Scripts

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Poetry (1.2.0b2) is installed now. Great!

To get started you need Poetry's bin directory (C:\Users\<REDACTED>\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Scripts) in your `PATH`
environment variable.

Alternatively, you can call Poetry explicitly with `C:\Users\<REDACTED>\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Scripts\poetry`.

You can test that everything is set up by executing:

`poetry --version`

Uninstalling Poetry seems to not delete C:\Users\<REDACTED>\AppData\Local\Packages\<PYTHON_APP>\LocalCache\local-packages\Scripts\poetry.exe though. It only deletes C:\Users\<REDACTED>\AppData\Local\Packages\<PYTHON_APP>\LocalCache\Roaming\pypoetry directory on my end.

Though quickly testing with the non MS Store Python, the behavior seems to be the same, so this may have to do with how we currently globally handle Windows on the install script.
