Update snazzy.conf from upstream

[Luflosi]

From https://github.com/connorholyday/kitty-snazzy/commit/272e522361f7125695cba66a6f1a713dcea63964. Is there some better method to update the themes? Doing this manually does not feel like a good solution. Maybe we could use git submodules?

I can see the problem but I don't think using submodules would be a good solution for three reasons:

• I don't think this is really a problem in general because themes don't change that often;
• not every theme is hosted on git (or have a kitty conf file), so it wouldn't be possible to track their changes (this is going to create a discrepancy on how you manage the themes);
• each theme has its own git structure, at that point the way you install a theme is going to change for each theme;

On the other hand, I understand that without a tracking mechanism one should rely on manual inspection of the original theme. Maybe a GitHub bot that tracks the changes of remotes and creates pull requests or creates issues? but I don't know how hard would it be to create this hypothetic bot.
