Document support for ssh over SOCKS5

[sorenisanerd]

Fixes #17754, surprisingly.

golang.org/x/net/proxy.FromURL (which Terraform uses to add support for HTTP and HTTPS) supports socks5 out of the box:

Thanks @sorenisanerd for this update and spotting that this functionality now exists. I plan to bring this to triage and hopefully get it reviewed, would you please sign the CLA so that we can use this submission? Thanks again!

[crw]

Hi @sorenisanerd, we would be happy to approve these changes once you sign the CLA. Once you have done that, I'll let the docs team do a once-over on the style and we will be set. Thanks!

Also, I wonder if it is worth updating to mention socks5h support? To be honest, I am not clear if that is fully supported by the new functionality or just recognized as a keyword that defaults to some more basic socks5 functionality (just because it is caught by the same case statement in that code snippet, above). I leave it to your judgement. Thanks!
