ref: #3466 (comment)

Now freedownloadmanager's installer.script should be simplified to (see ScoopInstaller/Extras#2220)

"installer": {
    "script": [
        "Expand-InnoArchive -Path \"$dir\\$fname\"",
        "Expand-InnoArchive -Path \"$dir\\$fname\" -ExtractDir '{code_CefInstallDir}' -Removal"
    ]
}

LGTM.

I am not sure how reliable would be to depend on curly brackets. But fur current use cases this is enough.

I've tested for freedownloadmanager, and it works fine. See attached PR.
