Update to catppuccin/palette v1.7.1

[sgoudham]

The next step in order to roll out our ANSI colour updates (catppuccin/catppuccin#1961) is to ingest them into this repository so that catppuccin/whiskers has access to them.

Worth noting that we have a workflow to automatically update the file as seen in #38 but I think some extra code changes are required for this one. E.g. the Flavor struct now needs to account for an extra ansiColors key:

rust/build.rs

Lines 42 to 48 in f9851c0

	#[derive(Debug, Deserialize)]
	struct Flavor {
	emoji: char,
	order: u32,
	dark: bool,
	colors: HashMap<String, Color>,
	}
