Fix PowerShell command echoing issues
When running PowerShell commands which contain the "
character, the current echo functionality (which naively doesn't escape those characters) will result in broken build scripts. This MR addresses that issue by explicitly escaping those characters when echoing commands in PowerShell.
Before
echo ".\build.ps1 "main.go""
.\build.ps1 "main.go"
After
echo ".\build.ps1 `"main.go`""
.\build.ps1 "main.go"
