Unable to get resourceFolder context keys to work

[miguelsolorio]

Testing #107638

I have this basic extension:

export function activate(context: vscode.ExtensionContext) {

	// notification
	const sayHello = vscode.commands.registerCommand('extension.helloWorld', () => {
		vscode.window.showInformationMessage('👋 Hello World!');
	});

	// commands
	vscode.commands.executeCommand('setContext', 'supportedFolders', ['test']);

	// context
	context.subscriptions.push(sayHello);
}

And also have the contribution set in the package.json like so:

		"menus": {
			"explorer/context": [
				{
					"command": "extension.helloWorld",
					"when": "explorerResourceIsFolder && resourceFolder in supportedFolders",
					"group": "navigation@1"
				}
			]
		}

And can't get the menu item to appear when right-clicking on a test folder, though if I remove the resourceFolder rule it'll show up so I'm wondering if I am either referencing it wrong here or if there is something else missing. I tried searching through our existing docs + issues and couldn't get much further.

resourceFolder and resourcePath are absolute "paths"

Here is an example that adds a Say Hello command to any folders/files in the root src folder (not on nested folder/files), and adds a Say Goodbye command to file/folder who's parent folder path ends with /test or \test

import * as paths from 'path';
import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
	const sayHello = vscode.commands.registerCommand('sayHello.command', () => {
		vscode.window.showInformationMessage('👋 Hello World!');
	});

	const sayGoodbye = vscode.commands.registerCommand('sayGoodbye.command', () => {
		vscode.window.showInformationMessage('👋 Goodbye World!');
	});

        // Only show Say Hello on folders/files in the root `src` folder (not in nested folders)
	const supportedFolders = [];
	for (const folder of vscode.workspace.workspaceFolders ?? []) {
		supportedFolders.push(paths.join(folder.uri.fsPath, 'src'));
	}
	// commands
	vscode.commands.executeCommand('setContext', 'supportedFolders', supportedFolders);

	// context
	context.subscriptions.push(sayHello, sayGoodbye);
}

	"contributes": {
		"commands": [
			{
				"command": "sayHello.command",
				"title": "Say Hello"
			},
			{
				"command": "sayGoodbye.command",
				"title": "Say Goodbye"
			}
		],
		"menus": {
			"explorer/context": [
				{
					"command": "sayHello.command",
					"when": "resourceFolder in supportedFolders",
					"group": "foo"
				},
				{
					"command": "sayGoodbye.command",
					"when": "resourceFolder =~ /(\\/|\\\\)test$/",
					"group": "foo"
				}
			]
		}
        }

Ah, since I am not too familiar with this it was a bit hard to figure out without an example. We should probably have this in the docs somewhere?

I added these new keys to the docs, with an example.
