Bug: debugpy command titles show as placeholders in Run/Debug UI

[CornHulio123]

With ms-python.debugpy 2025.18.0 the Run button dropdown / Run and Debug UI shows entries like:

• %debugpy.command.debugInTerminal.title%
• %debugpy.command.debugUsingLaunchConfig.title%
  instead of proper labels.

Regression:

• ✅ Works as expected with ms-python.debugpy 2025.16.0
• ❌ Broken with ms-python.debugpy 2025.18.0

Notes:

• Debugging still works (F5 launches current Python file); only the UI labels are broken.
• Tried “Developer: Reload Window” (no change).
• Downgrading debugpy to 2025.16.0 fixes immediately.

Environment:

• OS: Windows
• VS Code: 1.88.1 x64
• ms-python.python: 2025.20.0
• ms-python.debugpy: 2025.18.0 (broken), 2025.16.0 (ok)

Steps to reproduce:

1. Install/upgrade ms-python.debugpy to 2025.18.0
2. Open any Python file
3. Click the Run dropdown (top-right) or open Run and Debug
4. Observe placeholder labels instead of localized strings

This issue appears to be due to an accidental deletion of the package.nls.json file in a recent Commit 2601662, which is responsible for translating those UI placeholders.

You can manually restore the missing file to get proper text back:

• Get the file: Go to the project's repository, switch to the previous 2025.16.0 release branch, and download the package.nls.json file.

• Place it in your extension folder: Copy the downloaded package.nls.json file into your local extension installation folder. The path is typically similar to .vscode\extensions\ms-python.debugpy-2025.18.0-win32-x64\. You can also reach the directory by:

• Restart VS Code for the changes to take effect.

This should restore the translated command titles in your UI. Hopefully, the maintainers will revert this change or provide a proper fix soon.
