TUI - Improve how error message gets presented when rate limits like tokens per min or maximum context length gets execeeded.

[sangee2004]

gptscript version v0.0.0-dev-7ff3fa1f-dirty

Steps to reproduce the problem:

1. I am testing with an openai account which is in "Tier 1" (with $5 credit) billing tier.
2. When I hit rate limits for tokens per min or maximum context length , the error message presented in the TUI looks like they are unhandled exceptions .
