Mention HTML unit in file downloads section

[skyhirider]

🚀 Feature Proposal for the site or the documentation

https://www.selenium.dev/documentation/en/worst_practices/file_downloads/

HTMLunit has a mature interface for file downloads ( see https://htmlunit.sourceforge.io/apidocs/com/gargoylesoftware/htmlunit/attachment/AttachmentHandler.html )

It could be mentioned as many are looking to use Selenium for web scraping and file downloads and copying a link is not always possible, especially with more complex JavaScript sites.

Not sure if there is a better way to handle file downloads via Selenium currently that to use HTMLunit, it's driver and native input streams

Motivation

Took me quite a bit of time to figure out how to download files. Having at least a mention in the official docs would probably hell others save time.

Example

HtmlUnit and its driver can be used to intercept files as input streams and add custom logic that will handle and save them.

See https://github.com/SeleniumHQ/htmlunit-driver and https://github.com/HtmlUnit/htmlunit/blob/master/src/main/java/com/gargoylesoftware/htmlunit/attachment/AttachmentHandler.java

@skyhirider, would you like to send us a pull request with that suggestion?

[skyhirider]

@diemol I can, but saw there are several language files in the repo.

Presume English is good enough?

Any guidelines on what to write and how?
