fix(image_mcp.py): use consistant argument (#929)

[MaoSong2022]

fix argument error in MMMU_Pro benchmark, close #929

Hi, @MaoSong2022 ,

It looks like every other dataset do not set the arg names explicitly, so I don't think the modification is necessary.

[MaoSong2022]

the change is to keep the arguments consistent with ImageBaseDataset initialization. For now, only a few dataset implements this method.

• ImageBaseDataset initialization: def __init__(self, dataset='MMBench', skip_noimg=True)
• some other dataset initialization (such as MMGenBench): def __init__(self, dataset, **kwargs)
• this commit (related issue): def __init__(self, dataset='MMMU_Pro', skip_noimg=True)

the question is should we use consistent arguments when inheriting ImageBaseDataset, if the answer is yes, which format should we use.
