Rolling Expr claims to support timedelta but doesn't appear to

[CatchemAL]

Checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of Polars.

Reproducible example

    def rolling_std(
        self,
        window_size: int | timedelta,
        weights: list[float] | None = None,
        *,
        min_periods: int | None = None,
        center: bool = False,
        ddof: int = 1,
    ) -> Expr:

I'm aware that there are expressions such as rolling_std_by but many of the standard rolling expressions have type annotations suggesting they also support timedelta. Assuming they shouldn't, the following functions have type annotations that need correcting:

• Expr.rolling_sum [src]
• Expr.rolling_std [src]
• Expr.rolling_var [src]
• Expr.rolling_median [src]
• Expr.rolling_quantile [src]
• Expr.rolling_sum [src]

Log output

No response

Issue description

Type annotations appear to support timedelta but I am not convinced they do

Expected behavior

Probably just remove timedelta from annotations.

thanks @CatchemAL , I probably forgot to remove these when splitting things out into the _by variants
