Subject: [PATCH] fix(clipboard): connecting via vscpde's remote-ssh extension
 causes severe lag during yank and copy operations.  (#6664)

## Description

When connecting to a remote server via VSCode's Remote-SSH extension,
the `SSH_TTY` environment variable is not set. Consequently, both the
`vscode-neovim` extension (when using the remote Neovim instance) and
Neovim launched from VSCode's integrated terminal use the system
clipboard, resulting in severe lag.

Additionally, the `yanky.nvim` plugin synchronizes with the system
clipboard by default, regardless of whether the `clipboard` option is
set to an empty string (`""`). This causes similar performance issues as
described above.

Using the `SSH_CONNECTION` environment variable instead of `SSH_TTY` can
effectively resolve this issue.
