Dates not formatted in render.data_frame

@jcheng5 Perhaps this is expected and up to the user to format?

import pandas as pd
import numpy as np
from shiny import App, Inputs, Outputs, Session, reactive, render, req, ui


# Create a date range
dates = pd.date_range("20230101", periods=6)

# Create a DataFrame
data = pd.DataFrame(
    {
        "A": np.random.rand(6),  # numeric column
        "B": pd.Categorical(
            ["test", "train", "test", "train", "test", "train"]
        ),  # categorical column
        "C": dates,  # date column
    }
)

Reproduce the supplied Python example with render.data_frame using both DataGrid and DataTable, then trace how date columns are displayed. Determine whether the current output is expected and identify any existing tests or documentation covering date formatting; done means the behavior is resolved or clearly documented.
