Fix tools/infer_e2e_parallel.py crashing on startup with a TypeError

[Anai-Guo]

What

tools/infer_e2e_parallel.py cannot be run at all:

$ python tools/infer_e2e_parallel.py
Traceback (most recent call last):
  File "tools/infer_e2e_parallel.py", line 184, in <module>
    main()
TypeError: main() missing 2 required positional arguments: 'cfg_det' and 'cfg_rec'

The module's entry point is

if __name__ == '__main__':
    main()

but the function is declared def main(cfg_det, cfg_rec):.

Why removing the parameters is the right fix

Neither name is used anywhere in main()'s body. The two configs are built inside
OpenOCRParallel.__init__ (:30–:34), which is where the cfg_det / cfg_rec locals
actually live — a different scope:

class OpenOCRParallel:
    def __init__(self, drop_score=0.5, det_box_type='quad', max_rec_threads=1):
        cfg_det = Config('./configs/det/dbnet/repvit_db.yml').cfg
        cfg_rec = Config('./configs/rec/svtrv2/repsvtr_ch.yml').cfg
        self.text_detector = OpenDetector(cfg_det, numId=0)
        self.text_recognizer = OpenRecognizer(cfg_rec, numId=0)

and main() only does text_sys = OpenOCRParallel(drop_score=drop_score, det_box_type='quad').

The sibling end-to-end script tools/infer_e2e.py already declares def main(): with no
parameters and is called the same way, so this just brings the parallel variant in line
with it.

One line, no behaviour change beyond making the script runnable.
