Document browserURL

[paulirish]

Description of the bug

The docs don't really say what browserURL is.

It's not a browserWSEndpoint (which I do know..) but what is it? https://pptr.dev/api/puppeteer.connectoptions also doesn't describe it.

Is it just http://localhost:9222 ?

I'm really just asking for an example in the docs. :)

There are examples in npx chrome-devtools-mcp@latest --help but we need to add them to the readme.

Actually it is already in the README: https://github.com/ChromeDevTools/chrome-devtools-mcp?tab=readme-ov-file#connecting-to-a-running-chrome-instance

@sebastianbenz should we update the section to explain the browser URL in more details?

I think so, wdyt about #613?
