fix: Removed duplicate field definitions in some classes

[Sai-Suraj-27]

What does this PR do?

In some classes, some of the fields/attributes are defined multiple times. I think the duplicates can be removed:

Lines 163 to 168 in a0a3e2f

	overwrite_cache: bool = field(
	default=False, metadata={"help": "Overwrite the cached training and evaluation sets"}
	)
	overwrite_cache: bool = field(
	default=False, metadata={"help": "Overwrite the cached training and evaluation sets"}
	)
