Invalid ternary operator used in PowerShell script

[pGriffinPower]

While reviewing the PowerShell setup script provided by the observability agent, line 133:
$level = "$($env:log_level -eq $null ? 'warn' : $env:log_level)"

fails with: "Expected token '?' in expression or statement."

The problem is that PowerShell does not support the ternary ? : operator. This is invalid syntax in all versions of PowerShell, including 7+.

I strongly advise changing it to the following code "$level = $env:log_level ?? 'warn'."

I have not verified the subsequent install steps, but this should be addressed.

Thank you for your attention.
