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)

Debugger Configurations

`
        {
            "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": [],
        },

Additional Information

No response

No implementation files or tests are named. Start by locating validation for cppvsdbg launch configurations involving dumpPath and program; done when dump configurations are accepted without program while ordinary launch configurations still require it, or the dumpPath documentation clearly explains the exception.
