Fix logging output routing and added colorized logging (#205, #206)

[SaurabhCodesAI]

Fixes

• Fixes Logging outputs to stderr instead of stdout #205 by @TimidRobot
• Fixes Colorize logging based on log level #206 by @TimidRobot

Description

Fixed logging output routing so info/warning messages go to stdout and errors go to stderr. Also added colors to log messages so they're easier to read in the terminal.

Technical details

Replaced basicConfig() with dual handlers for proper output routing, then added a ColoredFormatter class with the ANSI color codes.

Tests

Run python scripts/1-fetch/gcs_fetch.py --help and you'll see colored log output routed correctly.

About the basicConfig thing, I tried keeping it at first but it messed with the new handlers, so I just replaced it entirely.

Used a dictionary for the colors since it was easier than a bunch of if statements.

Did both issues together since #206 needed #205 done first anyway.

Thanks @TimidRobot for the clear issue descriptions, made it much easier to understand what was needed!

Great work!

A couple of the comments are asking you to fix my own mistakes 🙃

Testing this was made a little more difficult due to the branch/PR being out of date (not synchronized with main). I suspect this is also why the changes to the update_readme function were included.

I apologize, I missed the "(if applicable)" part and checked those boxes without thinking. I'm still learning the open source contribution process and will be more careful with the checklist. Thanks for your valuable guidance.
