Prevent opening 2 tabs when Puppeteer.launch(headless: false)

[YusukeIwaki]

Step to reproduce

require 'puppeteer'

Puppeteer.launch(headless: false) do |browser|
  page = browser.new_page
  page.goto("https://github.com/YusukeIwaki/puppeteer-ruby")

  puts browser.pages.count # => 2
  sleep 10
end

Observed behavior

With this code, 2 tabs open.

Expected behavior

It would be better if only 1 tab open after Puppeteer.launch and browser.new_page.

Puppeteer (JS) also have the same behavior.
puppeteer/puppeteer#4298

Having an extra blank page uses no CPU and very little memory. I wouldn't worry about it.

It is right, however Playwright already improved it.
