When using 'dumpPath', 'program' is required yet unused

Environment

• OS and version: Windows
• VS Code: 1.93
• C/C++ extension: 1.21.6

Bug Summary and Steps to Reproduce

The program field is required yet unused when debugging

Steps to reproduce:
Create a debugger configuration that opens a .dmp file:

        {
            "name": "Open Dump File (Windows)",
            "type": "cppvsdbg",
            "request": "launch",
            "dumpPath": "e:\crash.dmp",
            "program": "unused field in case of opening dumps, that is required in the json",
            "args": [],
            "cwd": "${workspaceFolder}",
            "environment": [],
        },

This configuration works to open a dump, though as you can see program is not a requirement, yet the json requires it to be valid and allow the debugging.

Can this field be made optional in case dumpPath is filled in? (or at least add some note with the documentation of dumpPath)

        },

Non sono indicati file di implementazione né test. Inizia individuando la convalida delle configurazioni di avvio di cppvsdbg che coinvolgono dumpPath e program; il lavoro è completato quando le configurazioni di dump vengono accettate senza program, mentre le normali configurazioni di avvio continuano a richiederlo, oppure quando la documentazione di dumpPath spiega chiaramente l’eccezione.
