[REQUEST] Tweak default colors for RichHandler

[alexprengere]

Hello, first of all, thank you for rich! I use it in pretty much all my projects.

I have a very minor suggestion regarding the default colors for logging levels.
I know we can customize them using themes (and I already do!).
I use mostly info/warning/error levels for logging, and depending on the terminal used, warnings and errors render almost identically.

When googling "Python colored logs", the top solutions (in my case) use yellow-ish for warnings and red for errors.
Granted, many of the top results use coloredlogs, but in any case I see:

• stack overflow top answer
• PyPI coloredlogs
• a blog post
• another blog post
• PyPI colorlog

So I was wondering if you would be willing to tweak the default 'logging.level.warning' to something closer to yellow, to be more in line with this, and give a bit more distinction to warnings and errors.
Anyway, I am perfectly happy with customization through themes!
