Added workspaceFolders search

[m4ss1m0g]

When open in a workspace the extension search on first workspace folder using the deprecated vscode.workspace.rootPath.
I have changed rootPath with the array string of all workspace folders.

Now the extension correctly read ALL workspace folders.

To test the actual behavior create a folder with this structure.

├── **my.code-workspace**
├── **mySolution.sln**
├── README.md
├── Docker
│   ├── Dockerfile
├── src
│   ├── Domain
│   │   ├── **Domain.csproj**
│   │   ├── bin
│   │   └── obj
│   ├── Infrastructure
│   │   ├── **Infrastructure.csproj**
│   │   ├── bin
│   │   └── obj
│   ├── NetCoreWeb
│   │   ├── **Web.csproj**
│   │   ├── Api
│   │   ├── Program.cs
│   │   ├── Startup.cs
│   │   ├── appsettings.json
│   │   ├── bin
│   │   ├── wwwroot
│   └── VueAPP
│       ├── node_modules
│       ├── package.json
│       ├── src
│       ├── tests
│       ├── tsconfig.json
│       ├── vue.config.js
│       └── yarn.lock
└── tests
    └── MyTests
        ├── **Test1.csproj**
        ├── Consts.cs
        ├── bin
        └── obj

Where the workspace is

{
	"folders": [
		{
			"path": "src\\VueAPP",
			"name": "🧃 VueJS"
		},
		{
			"path": "src\\Domain",
			"name": "🧱 Domain"
		},
		{
			"path": "src\\Infrastructure",
			"name": "🌉 Infrastructure"
		},
		{
			"path": "src\\NetCoreWeb",
			"name": "🕸️ Web"
		},
		{
			"path": "tests\\MyTests",
			"name": "🧪 Tests"
		},
		{
			"path": ".",
			"name": "🌵 Root"
		}
	]
}

Notice the last workspace node Root witch include ALL
