Cannot configure provided tasks

[planger]

Bug Description:

In a Theia application that has VS Code extensions providing tasks (e.g. for npm, grunt, etc.), they are correctly shown when executing Run Task.... However, when I select a provided task folder (e.g. npm), I cannot click on the cogwheel to configure them in my tasks.json.

Steps to Reproduce:

1. Open Blueprint (or any other Theia application with VS Code extension that contribute provided tasks)
2. Open a workspace where a provided task is discoverable (e.g. a folder with an npm module, like a Theia application)
3. Select npm
4. Try to click on the cogwheel

configure-provided-tasks.mp4

What happens: nothing
What should happen: the provided task is copied over to tasks.json for further customization.

Additional Information

• Operating System: Ubuntu Linux
• Theia Version: 1.43.0
