Fix missing ** spread on _make_options in propagate-options test

The multi-line _make_options(...) call in
test_should_propagate_process_options_to_spawned_cli was missed by my
earlier sed pass that converted CopilotClient(_make_options(...)) to
CopilotClient(**_make_options(...)) — the regex only matched single-line
forms. Add the missing ** here.
