Log ChatGPT user ID for feedback tags (#13901)

There are some bug investigations that currently require us to ask users
for their user ID even though they've already uploaded logs and session
details via `/feedback`. This frustrates users and increases the time
for diagnosis.

This PR includes the ChatGPT user ID in the metadata uploaded for
`/feedback` (both the TUI and app-server).
