Map drive letter to local folder

We have a group policy or something at work that tries to add some network drives at startup. This doesn't always work, espacially when working remotely.

This causes an error when using the azure cli, resulting in this type of error.

❯ az account show

Mapping the failing drive letter to a local folder solves the problem, like this

subst p: c:\temp

To remove the mapping, do

subst p: /D
