[js] download files from remote server

[titusfortner]

Status

In draft because downloadFile does not yet work.

@harsha509 I updated this as best I can figure, but downloadFile is a copy/paste from ChatGPT and I'd be shocked if it worked. Can you help me figure out the right implementation for that functionality?

Description

• adds capability enableDownloads
• errors if using method without setting capability
• getDownloadableFiles returns direct list of names
• downloadFIle — needs help
• downloadFile creates directory if does not exist
• deleteDownloadableFiles deletes all files

Motivation and Context

implement #11657

Hello @titusfortner , is using JS to download files from Remote WebDriver still not supported?

[titusfortner]

It should work. Are you having a problem?

It should work. Are you having a problem?

I'm always getting the below error message when trying to downloadFile

 Uncaught WebDriverError WebDriverError: Cannot find file [[selenium-java-4.21.0.zip]] in directory C:\Users\admin\AppData\Local\Temp\1\uuid13931905917359662002f7930a56-f43c-4f3d-b955-d6cfd9cafa88\download16040450071988999621.

I found this PR from changelog and I have noticed you said the downloadFile should not work.
After comparing codes with the trunk, there's nothing new, so I believe it's still not working.
