[stephen-huan]

The first commit fixes cross-references in the man page.

The second commit corrects the file type color descriptions to match current source.

Lines 110 to 123 in e7882ce

	#[rustfmt::skip]
	file_type: Some(FileType {
	image: Some(Purple.normal()),
	video: Some(Purple.bold()),
	music: Some(Cyan.normal()),
	lossless: Some(Cyan.bold()),
	crypto: Some(Green.bold()),
	document: Some(Green.normal()),
	compressed: Some(Red.normal()),
	temp: Some(White.normal()),
	compiled: Some(Yellow.normal()),
	build: Some(Yellow.bold().underline()),
	source: Some(Yellow.bold()), // Need to discuss color
	}),

P.S.: The version packaged in nixpkgs has $version instead of the version number; I've opened NixOS/nixpkgs#345185.

I've also incorporated this change into the flake package output.

When we're moved to clap fully, we can give a more interesting version number through it by getting it from Cargo.toml and appending -dev or something like that, without crane it feels like a bit too much effort to keep in sync.
