+.SYNOPSIS
+    Repairs shell integration for vscode-powershell.
+.DESCRIPTION
+    Repairs shell integration for vscode-powershell <= v2024.2.2 by creating a folder and a symlink.
+    Needs to be run again after any update of VSCode >= 1.94.
+    Requires admin rights. Runs on any PowerShell version or supported OS platform.
+.NOTES
+    VSCode 1.94++ moved the shell integration scripts to a different folder.
+    As a result, the PowerShell Extension doesn't initialize correctly.
+    This seems to be fixed in v2024.5.0-preview.
