Incorrect PowerShell commands on [User Guide] Quick Start Phase 2 GitHub wiki page

[jon-krueger]

Under sections 2.2.2.1 GitHub with Bicep and 2.2.2.2 GitHub with Terraform the PowerShell command to create the output directory is incorrect.

New-Item c:\accelerator\output creates a file with the name output. The PowerShell command should be New-Item -ItemType "directory" c:\accelerator\output

or for Linux

New-Item -ItemType "directory" ~/accelerator/output
