[Question] Proxy documentation

Describe your question
I've tried getting my proxy service to work with Botright. I have it working with a urllib example and with normal playwright. When I try to convert it to a string and use it in Botright, it does not connect. Can you please add a working example to the Botright documentation?
`botright.modules.proxy_manager.ProxyCheckError: Could not get IP-Address of Proxy (Proxy is Invalid/Timed Out)

import asyncio
import botright


async def main():
    botright_client = await botright.Botright()

    # Proxy configuration
    proxy = "[username]:[password]@[address]:[port]"

    # Launch the browser with proxy settings
    browser = await botright_client.new_browser(
        proxy=proxy,
        args=[
            "--ignore-certificate-errors",
        ],
    )

    # Create a new page and navigate to the desired URL
    page = await browser.new_page()
    await page.goto("https://www.google.com")
    print(await page.title())

    await botright_client.close()


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

Expected behavior
Connects to proxy successfully.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Windows
• Version 11

Additional context
Adding http:// from the start does not change anything.
Removing args does not change anything

Start by reviewing the existing Botright documentation and the proxy handling around botright.modules.proxy_manager.ProxyCheckError, then compare it with the supplied Python and Playwright example. Done means the documentation contains a working authenticated proxy example and explains the expected proxy format and successful connection behavior.
