Fix wrong (non-existing) checkpoints

[ydshieh]

What does this PR do?

The previous values are simply wrong.

(which also cause problems for tiny model creation)

apparently there are some more places to update (to make modular check works)

It looks like the modular is creating

Salesforce/instructblipvideo-flan-t5-xl

based on the block

@auto_docstring(checkpoint="Salesforce/instructblip-flan-t5-xl")
class InstructBlipVideoVisionConfig(InstructBlipVisionConfig):
    pass

and complain it doesn't match the actual one that should be used

Salesforce/instructblip-flan-t5-xl

@vasqu @Cyrilvallez

Is the only way is just to remove the following 2 blocks from modular file

@auto_docstring(checkpoint="Salesforce/instructblip-flan-t5-xl")
class InstructBlipVideoVisionConfig(InstructBlipVisionConfig):
    pass


@auto_docstring(checkpoint="Salesforce/instructblip-flan-t5-xl")
class InstructBlipVideoQFormerConfig(InstructBlipQFormerConfig):
    pass
