Playwright breaks if serde_json is used with arbitrary-precision feature.

[lukesneeringer]

Playwright fails to load any browser correctly if one has the following dependency in Cargo.toml

serde_json = { version = "1.0.66", features = [ "arbitrary_precision" ] }

If one removes features = [ "arbitrary_precision"], then it works.
This occurs on at least the async-std and tokio executors.

I would love to submit a PR to fix this bug, but I have not the foggiest idea how to get started fixing it. :-/

Reproduction case

use std::env;

use playwright::Playwright;

#[async_std::main]
async fn main() -> Result<(), playwright::Error> {
  if env::var("TOY_LOG").is_err() {
    env::set_var("TOY_LOG", "warn");
  }
  pretty_env_logger::try_init_custom_env("TOY_LOG").unwrap();

  let playwright = Playwright::initialize().await?;
  playwright.prepare()?; // Install browsers
  log::debug!("Creating browser.");
  let chromium = playwright.chromium();
  let browser = chromium.launcher().headless(false).launch().await?;
  log::debug!("Creating context.");
  let context = browser.context_builder().build().await?;
  let page = context.new_page().await?;
  page.goto_builder("https://en.wikipedia.org/").goto().await?;

  log::info!("Success");
  Ok(())
}

Logs

Here are the logs you get if you try to load with arbitrary_precision feature turned on:

 DEBUG toy                              > Creating browser.
 DEBUG playwright::imp::core::transport > SEND Req { id: 1, guid: "browser-type@22850ecee7392c91106a2feb3a1d26d5", method: "launch", params: {"headless": Bool(false)} }

Traceback

And here is the traceback you get if you change the appropriate ? to .unwrap() and run with RUST_BACKTRACE=1:

[lukesneeringer]

I am looking at this further and the root issue appears to be serde-rs/json#559.

I am spelunking through the playwright-rust code to see if I can determine where to apply the workaround and found the error within a deserializer, but could not determine where the deserialization call was, which is where the workaround goes.
