Fix Rosé Pine colors

Description

Update Rosé Pine files to fix the issues reported on #439 and #442.

The iTerm2 files for Rosé Pine theme and it's variants were downloaded from the theme's official repository at https://github.com/rose-pine/iterm

I've tested on iTerm2 and they look good.

Thank you!

This PR only appears to partially fix #442 (but #439 is fixed). Rosé Pine Dawn is fixed, and the colours in Rosé Pine are untouched. Rosé Pine Moon has the brights fixed but the regular colours are untouched.

Hi @00-kat. I thought I had fixed both issues, but it seems I missed something.

Would you mind commenting on issue #442 and providing more details about which colors don’t seem right? Maybe I can help fix it.
