Ruby 3.0.1 - uninitialized constant Selenium::WebDriver::ServiceManager::URI

[flanger001]

🐛 Bug Report

On Ruby 3.0.1, when the stdlib uri package has not already been required, selenium-webdriver v4.0.0.rc1 throws this error when creating a browser driver:

/path/to/project/selenium/.bundle/ruby/3.0.0/gems/selenium-webdriver-4.0.0.rc1/lib/selenium/webdriver/common/service_manager.rb:73:in `uri': uninitialized constant Selenium::WebDriver::ServiceManager::URI (NameError)

This can be fixed by including the line require "uri" at this line: https://github.com/SeleniumHQ/selenium/blob/trunk/rb/lib/selenium/webdriver.rb#L26, which I will open a PR for shortly.

To Reproduce

Executable steps are below, but this is the plain-language general idea:

• Create and navigate to a project directory
• Initialize a Gemfile
• Add a local Bundler configuration
• Install gems
• Create a Ruby script requiring selenium-webdriver and initializing a browser driver
• Run the script with bundle exec

Expected behavior

• Firefox window appears briefly and then disappears
• Program runs without errors

Bump - I modified the repro script to be a bit more idempotent.
