Allow the "Print" command to include a header and footer, and to customize them via a template

[Roman-Hordynskyi]

Pls add displayHeaderFooter field to https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/print/PrintOptions.html

Please note that this repository is not related to Selenium, but we definitely miss those options in WebDriver classic. Given that our current priority is on WebDriver BiDi, we will most likely address w3c/webdriver-bidi#741 first. After that, we can consider whether porting the logic to WebDriver classic is still feasible.

Beside this flag we would need to support the customization of the content of both elements by using a template.
