ssh remoting: Fix wrong working directory for SSH terminals (#19672)

Before this change, we would save the working directory *on the client*
of each shell that was running in a terminal.

While it's technically right, it's wrong in all of these cases where
`working_directory` was used:

- in inline assistant
- when resolving file paths in the terminal output
- when serializing the current working dir and deserializing it on
restart

Release Notes:

- Fixed terminals opened on remote hosts failing to deserialize with an
error message after restarting Zed.
