Inconsistent `withscore` and `score_cast_func` Parameters Between `zrevrange` and `zrevrank`

Description

Hi everyone,
I noticed an inconsistency between the zrevrange and zrevrank functions regarding score casting behavior.

The zrevrange function has both withscore and score_cast_func parameters:

def zrevrange(
        self,
        name: KeyT,
        start: int,
        end: int,
        withscores: bool = False,
        score_cast_func: Union[type, Callable] = float,
    ) -> ResponseT:

According to the docstring, the score_cast_func is a callable used to cast the score return value.

However, the zrevrank function only has a withscore parameter and casts to float by default, this discrepancy led to the following code in my project:

x = redis_client.zrevrange(
         "test",
        0,
        -1,
        withscores=True,
        score_cast_func=int,
    )

y = redis_client.zrevrank(
        "test",
        "test",
        withscore=True,
    )
y = int(y)

Question
Why does the zrevrange function offer the flexibility of score_cast_func while zrevrank does not? Given the similar nature of these functions, shouldn’t they both support the same score casting logic for consistency?

Proposal
For a more consistent API, I suggest adding the score_cast_func parameter to the zrevrank function, similar to its implementation in zrevrange.
