* feat(cwd-pane): Refactor spawn_terminal to use cwd by default

* feat(cwd-pane): Fix tests and lints

Co-authored-by: Quentin Rasmont <qrasmont@gmail.com>

* feat(cwd-pane): Fix formatting

* feat(cwd-pane): Refactor child pid fetching to handle errors better

Instead of panicking when transfering the process id of the forked child
command we just return an empty process id.

* feat(cwd-pane): Add non Linux/MacOS targets for the get_cwd method.

This will allow Zellij to compile on non Linux/MacOS targets without
having an inherited cwd.

* feat(cwd-pane): Refactor spawn_terminal method to use ChildId struct.

The spawn_terminal methods been refactored to use the ChildId struct in
order to clarify what the Pid's returned by it are. The documentation
for the ChildId struct was improved as well.

* feat(cwd-pane): Fix tests/lints
