Thank you for your work.
The issue with this is that most of the configs that exist already are generated through scripts and individually adding just a colorscheme is not the approach that is used here.
To get a general Idea of how it is done you can look into the scripts/ and also the files for each extra that is generated is inside lua/solarized-osaka/extra.
If the same thing can be replicated with a script so if we change some colors in the future this would be considered.

One last thing is that not to add information on how to use this Extra inside the repository's README.md.
The focus here is the actual colorscheme not all the extras but those are added as a bonus and mentioned in the README if someone needs them from there.

The README.md is separate in their respective dirs but I don't think that is desired here as this would be required for every other extra as well but i'll leave this up to the maintainer.

I'm closing the other Pull Request for eza as well as this contains those changes plus the additional Starship config that you've added.

Seems abandoned. Closing.
