[🚀 Feature]: Alert Page of Selenium Docs need work

[rpallavisharma]

Feature and motivation

The Alert page of the Selenium documentation requires improvement. Both in content and for examples shown for different programming languages. Some of the programming languages do not have complete code.
Also it is advisable that the example code used in documentation should be similar across languages.
The link to the page is - https://www.selenium.dev/documentation/webdriver/interactions/alerts/
