gtk: fix +new-window --working-directory inferrence.

If the CLI argument `--working-directory` is not used with
`+new-window`, the current working directory that `ghostty +new-window`
is run from will be appended to the list of configuration data sent
to the main Ghostty process. If `-e` _was_ used on the CLI, the
`--working-directory` that was appended will be interpreted as part of
the command to be executed, likely causing it to fail.

Instead, insert `--working-directory` at the beginning of the list of
configuration that it sent to the main Ghostty process.

Fixes #11356
