build command doesn't collect playwright binary files

[farshadz1997]

Description

I have created a GUI for my app that uses Playwright, it works well until I have built it with the build command flet build windows it builds the app without any problem and runs it without error but when Playwright wants to launch the browser it returns an error, I investigated and found the problem. Playwright has node.js binary in this path: C:\Users\%user%\AppData\Roaming\Python\Python312\site-packages\playwright\driver\node.exe but felt doesn't collect it to include it in __pypackages__ in the assets of the app so it can not launch the browser, I tried adding it manually in the archive file located in: <build directory>\build\windows\data\flutter_assets\app\app.zip Then I removed the temp folder and relaunched the app and it worked flawlessly. I have to notice that I didn't have this problem with flet pack command.

Code example to reproduce the issue:

from playwright.async_api import async_playwright, Playwright, BrowserContext

async def create_context() -> BrowserContext:
    ignore_args = [
        "--enable-automation",
        '--disable-extensions'
    ]
    args = [
        "--disable-blink-features=AutomationControlled",
        "--webrtc-ip-handling-policy=disable_non_proxied_udp",
        "--start-maximized",
        "--ignore-certificate-errors",
        "--disable-infobars",
    ]
    playwright = await async_playwright().start()
    chromium = playwright.chromium
    context = await chromium.launch(
        channel="chrome",
        headless=False,
        ignore_default_args=ignore_args,
        args=args,
        chromium_sandbox=True,
        java_script_enabled=True
    )
    return context

I expected that the felt build command would collect binary files of libraries like the pack command.
