v2022.4.0 regression: The Python path in your debug configuration is invalid.

[dgrunwald]

Issue Type: Bug

Behaviour

Expected vs. Actual

When launching the debugger, the error "The Python path in your debug configuration is invalid." pops up.
This is a regression in v2022.4.0; the same launch configuration worked correctly in v2022.2.1924087327.

Additionally, sometimes the file .vscode\extensions\ms-python.python-2022.4.0\pythonFiles\get_output_via_markers.py is opened in notepad++ (the default associated editor when double-clicking a .py file on my machine). It seems that whatever is trying to automatically run this script is instead just opening it. I'm not sure if this is related to the failure to launch the debugger.

Steps to reproduce:

This is the launch configuration in question:

        {
            "name": "rfgscript: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "python": "${workspaceFolder}/bin/rfgscript.exe",
            "console": "integratedTerminal"
        },

The file "rfgscript.exe" exists and is a custom application that loads python37.dll at run-time (via LoadLibrary). Note: python37.dll is not in the same directory as the custom .exe. The custom application accepts the same command-line arguments as the usual python.exe.

Duplicate of #18835

[dgrunwald]

Some of my configs had:
"python": "${workspaceFolder}/bin/rfgscript",

It seems that with the new version (v2022.5.11021002) the .exe file extension is required, otherwise I'm still getting the "The Python path in your debug configuration is invalid." error.
This makes it troublesome to reuse the launch config across platforms (Windows/Linux).

[karrtikr]

Working on adding back support for that with #18920.

[karrtikr]

Fix should be out in the pre-release version of the extension in a day, use the following to try it out:

@dgrunwald can you try out the latest prerelease version to see if this is fixed or not? Thanks.
