we can generate a vscode URI that when triggered will open in vscode the sql-server extension and fill out all of the fields and have the user just click "connect"

something like this:

```cs
var sqlServer = builder.AddSqlServer("sql-server")
.WithDataVolume("data");

sqlServer.WithCommand("open-in-vscode", "Open in VS Code", async context =>
{
var rawConnectionString = await sqlServer.Resource.GetConnectionStringAsync();
if (string.IsNullOrEmpty(rawConnectionString))
{
return new ExecuteCommandResult
{
Success = false,
ErrorMessage = "Connection string is not available."
};
}

VsCode.OpenSqlServerInVsCode(rawConnectionString);
return new ExecuteCommandResult { Success = true };
});
```

and the magic:
```cs

using System.Diagnostics;

using Microsoft.Data.SqlClient;

namespace Prevention.SecurityForAI;

public class VsCode
{
public static void OpenSqlServerInVsCode(string rawConnectionString)
{
var connectionString = new SqlConnectionStringBuilder(rawConnectionString);
string server = Uri.EscapeDataString(connectionString.DataSource);
string database = Uri.EscapeDataString(connectionString.InitialCatalog);
string userId = Uri.EscapeDataString(connectionString.UserID);
string password = Uri.EscapeDataString(connectionString.Password);

var vscodeUri = new Uri($"vscode://ms-mssql.mssql/connect?server={server}&database={database}&authenticationType=SqlLogin&user={userId}&password={password}&trustServerCertificate=true");
var process = Process.Start(new ProcessStartInfo
{
FileName = vscodeUri.ToString(),
UseShellExecute = true
});
}
}
```

this requires the https://marketplace.visualstudio.com/items?itemName=ms-mssql.mssql VsCode extension


@eerhardt / @eerhardt / @davidfowl is this out-of-scope here? should I create a separate issue for this? Maybe having a VsCode extention point that can open UI extensions for specific container based resources

### Describe the solution you'd like

I think adding a URL for the resource would be more naturally but I wasn't sure how to get the connection-string to the `AddUrl` method since it doesn't seem to support async flows.

My current solution is to add a command on the SQL server resource that when invoked will open vscode.

public API (via extension method):
```cs
public static IResourceBuilder WithOpenInVsCodeCommand(this IResourceBuilder builder);
```
