Reports Missing closing '}' on a if statement when not all on one line or the { not on the next line with powershell version 5

Inizia riproducendo i tre layout delle parentesi graffe dell’issue con PowerShell 5.1 tramite l’estensione VS Code, quindi confronta la diagnostica con PowerShell 7. L’issue è completata quando la forma multilinea valida non segnala più la mancanza di una parentesi graffa di chiusura, mentre le forme già funzionanti rimangono valide.

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

When running the following simple script:
`$ben = $true

if ($ben) {
Write-Output "ben"
}
`

the extension throws this error:

Missing closing '}' in statement block or type definition.
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MissingEndCurlyBrace

if the script looks like this:
`$ben = $true

if ($ben)
{
Write-Output "ben"
}`

or this:
`$ben = $true

if ($ben) { Write-Output "ben" }
`

it works.
Or if I switch to version 7 of powershell.
