Should st.experimental_user.email local value be test@example.com?

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

Currently st.experimental_user.email returns test@localhost.com when run locally (cite docs).

However, a more standard and correct approach is to use example.com domain (cite) which is safer.

Should we switch?

Reproducible Code Example

import streamlit as st

st.write(st.experimental_user.email)

Steps To Reproduce

1. Run the code example in a local environment

Expected Behavior

I see test@example.com which is standard

Current Behavior

I see test@localhost.com, which might not be totally safe and isn't a standard approach.

Is this a regression?

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

Debug info

• Streamlit version: 1.25
• Python version: 3.11
• Operating System: MacOS
• Browser: Chrome
