terminal: Resolve env based on the project dir on the target (#41867)

Prior to this change we would always resolve envs when spawning a new
terminal window based on the inherited CLI environment. This works fine
as long as we open a new Zed instance in the terminal when using it
locally only. When using Zed connected to a remote server, it would not
be meaningful however. WIth this change, we correctly ping the remote
for the project-local envs and use that instead. This change should also
fix a pesky issue when updating Zed - after Zed restarts, opening a new
terminal window will not run `direnv` for example.
