Fish completion delete session (#5317)

* Add session completion for "delete-session"

Close #5316

* Force default value for CARGO_TARGET_DIR

Since we did not approved and maintain #2611

* Move `xtask run`'s specific output to stderr

That way command output can be redirected without garbage e.g.:
`cargo xtask run -- setup --generate-completion fish > ~/.config/fish/completions/zellij.fish`
