Add Button to Open VS Code and Pass Generated Devcontainer Output

[nkkko]

Is your feature request related to a problem? Please describe.
Currently, the tool generates a devcontainer.json file that users must manually download and set up. Adding a button that directly opens the repository in VS Code from the browser and passes the generated devcontainer.json would streamline the process, making it more user-friendly.

Describe the solution you'd like

• Add a new button to the interface that, when clicked, opens VS Code with the current repository and passes the generated devcontainer.json.
• Utilize the vscode:// URL protocol to achieve this functionality, allowing seamless integration between the browser and VS Code.

Describe alternatives you've considered

• Providing manual download instructions, which requires additional steps and is less convenient.
• Creating an extension for VS Code, but it would require users to install additional software.

Additional context

• This feature will significantly improve the workflow for developers by reducing the setup process.
• Ensure that the new button is prominently displayed alongside the generated devcontainer.json output.
• Implement fallback logic to guide users in case the vscode:// protocol is not supported in their setup.

This new feature will enhance user experience by enabling quick and easy setup of development environments directly from the browser.
