Update error message to show dataframes and charts (when used as widgets) can't be assigned values through Session State

Checklist

• I have searched the existing issues for similar issues.
• I added a very descriptive title to this issue.
• I have provided sufficient information below to help reproduce this issue.

Summary

For the current streamlit-nightly and soon-to-be 1.35.0, we've introduced turning dataframes and some charts into widgets. Their values cannot be assigned through Session State.

Reproducible Code Example

import streamlit as st
import plotly.express as px

df = px.data.iris() # iris is a pandas DataFrame
fig = px.scatter(df, x="sepal_width", y="sepal_length")

st.session_state.x = {}
x = st.plotly_chart(fig, use_container_width=True, key="x", on_select="rerun")

Steps To Reproduce

Run the code and observe the (expected) error:

streamlit/lib/streamlit/elements/utils.py

Lines 43 to 46 in 1b73b44

	SESSION_STATE_WRITES_NOT_ALLOWED_ERROR_TEXT = """
	Values for st.button, st.download_button, st.file_uploader, st.data_editor,
	st.chat_input, and st.form cannot be set using st.session_state.
	"""

Expected Behavior

The error message should include the newly introduced read-only widgets: st.dataframe, st.vega_lite_chart, st.altair_chart, and st.plotly_chart.

Current Behavior

Error displayed from here:

SESSION_STATE_WRITES_NOT_ALLOWED_ERROR_TEXT = """
Values for st.button, st.download_button, st.file_uploader, st.data_editor,
st.chat_input, and st.form cannot be set using st.session_state.
"""

Is this a regression?

• Yes, this used to work in a previous version.
