processId as string fails to attach on Windows since v2.1.2 #335

Since version 2.1.2, the attach request on Windows no longer works correctly when using ${command:pickProcess}. It appears there is a type mismatch: the debugger seems to expect an integer for the processId, but VSCode's ${command:pickProcess} returns the ID as a string.

Environment:

OS: Windows
Plugin Version: 2.1.2 (and newer)
VSCode Version: 1.108.0

Steps to Reproduce:

Use the following configuration in launch.json:

{
  "name": "Lua: Attach",
  "type": "lua",
  "request": "attach",
  "processId": "${command:pickProcess}"
}

Actual Behavior:

The debugger fails to attach silently. The plugin fails to attach when processId is a string (which is the default output of ${command:pickProcess}).

Expected Behavior:

The plugin should handle the processId as a string or automatically convert it to an integer to maintain compatibility with the built-in VSCode process picker.

Workaround found:

If I manually hardcode the processId as an integer (e.g., "processId": 1234), the plugin attaches and works perfectly. However, this is not a viable solution for dynamic debugging.
