Tabulator: error when editing a table that contains a column with dtype `datetime64[ns, UTC]`

[maximlt]

When a DataFrame contains a column with dtype datetime64[ns, UTC], editing a value in the DataFrame through the Tabulator widget raises an Exception.

import pandas as pd
import numpy as np
import panel as pn
pn.extension('tabulator')

data = {'datetime_utc': pd.date_range(start='2024-01-01', end='2024-01-05', freq='D')}
df = pd.DataFrame(data)
# Convert the dtype of the datetime column to datetime64[ns, UTC]
df['datetime_utc'] = df['datetime_utc'].dt.tz_localize('UTC')
df["test"] = ""
table = pn.widgets.Tabulator(df)
table.servable()

Traceback:
