Register 'workbench.action.files.openFileFolder' VS Code command

[RomanNikitenko]

What it does

Add support for workbench.action.files.openFileFolder built-in command: #8750

The command should be available for running for:

• the browser version since Theia dialog supports the feature
• the Electron version if the system is OSX

How to test

My test extension can be used for testing:

1. Clone https://github.com/RomanNikitenko/vscode-test-extension.git
2. Build the extension using yarn and copy it to theia/plugins folder.
3. Start Theia and open a workspace folder.
4. F1 => run Test 'workbench.action.files.openFileFolder'

a dialog should be displayed which allows to open a file or a directory

@RomanNikitenko, checked test extension on Browser Example, Electron Example and VS Code.
Got the following behavior:

• Theia Browser Example:

openFileFolder-theia.mp4

• Theia Electron:

openFileFolder-electron.mp4

• VS Code:

openFileFolder-vscode.mp4

Let me know if there should be an additional use cases that need to be checked.

The changes look good to me, the open dialog that supports files and folders should only be available in the browser, and macos on electron 👍
