docs: fix stale storage path in CLI help, remove misleading codecov badge (#23)

- download-extract's docstring (shown via --help) said files are
  stored under gtfs_data/YEAR/MONTH/DAY, but the real constant is
  GTFS_ARCHIVE_FOLDER = 'gtfs_archive' (config.py). Fix the path in
  the help text.
- Removed the codecov badge: there are no test files anywhere in this
  repo (deleted in a past commit) and CI.yml only builds/pushes the
  Docker image, so codecov never receives real coverage data. Kept
  the CI build-status badge since it does reflect a real, accurate
  signal (whether the image build/deploy succeeded).
