[BUG] Ungoogled Chromium not found

[telmocrp1]

Thanks a lot for the work of this repo, it's a goldmine 🚀

Describe the bug
I followed the installation guide but I still have this error:
[WARNING] Ungoogled Chromium not found. Recommended for Canvas Manipulation. Download at https://ungoogled-software.github.io/ungoogled-chromium-binaries/

But ungoogled chromium is installed:
type ungoogled-chromium
ungoogled-chromium is /usr/bin/ungoogled-chromium

Code Sample
If applicable, add a code sample to replicate the bug.

test code:

import asyncio
import botright

async def main():
    botright_client = await botright.Botright()
    # Add the path to your Chromium-based browser here
    browser = await botright_client.new_browser()
    page = await browser.new_page()

    await page.goto("https://google.com")

    await botright_client.close()

if __name__ == "__main__":
    asyncio.run(main())

To Reproduce
Steps to reproduce the behavior:

1. Install Botright
2. Install Playwright
3. Install UC chromium
4. See error
