Update image in README #3843
Description
I noticed the hero image on the code-server docs is an older release of code-server - maybe keep that current to alleviate any confusion.
Mark brought up a good point saying the image in the README (also shows up in code-server docs on website) shows a very old version of code-server.
It's not worth automating IMO but we could update the image and remove any version references so it does not look outdated or cause confusion.
