Remove set-visited-file-name for remote docker file

[nohzafk]

Remove it will make things just work, keeping buffer as a non-file buffer

• aphelia formatter will work with remote file
• use set-visited-file-name will result in saving the file twice, and we have to deal with buffer modtime, and unsaved change.
• keep the same logic as remote SSH file

Update README about how to use formatter with remote file.
