timetable-bin: add missing runtime deps (4.0-2)

Upstream 4.0 replaced python-webuntis with pyotp for authentication and
unconditionally imports libsecret (credential storage) and WebKitGTK 6.0
at startup. Add python-pyotp, libsecret and webkitgtk-6.0 to depends.

Stop bundling the webuntis wheel from the next artifact build on; the
existing 4.0 artifact is reused as-is (its bundled copy is unused and
inert).
