In a PKGBUILD file b2sums, cksums and architectures are not highlighted

Problem

Source: https://man.archlinux.org/man/core/pacman/PKGBUILD.5.en

In the list below there should be b2sums and cksums.

vis/lua/lexers/pkgbuild.lua

Lines 48 to 55 in b68b822

	lex:add_rule('constant', token(lexer.CONSTANT, word_match{
	-- We do *not* list pkgver srcdir and startdir here.
	-- These are defined by makepkg but user should not alter them.
	'arch', 'backup', 'changelog', 'checkdepends', 'conflicts', 'depends', 'epoch', 'groups',
	'install', 'license', 'makedepends', 'md5sums', 'noextract', 'optdepends', 'options', 'pkgbase',
	'pkgdesc', 'pkgname', 'pkgrel', 'pkgver', 'provides', 'replaces', 'sha1sums', 'sha256sums',
	'sha384sums', 'sha512sums', 'source', 'url', 'validpgpkeys'
	}))

But you can also put an architecture after if you add an underscore. I'm pretty sure any architecture is valid for expandability so depends_insertfuturearchitecturehere is also valid.
Here's the list of them: source, depends, makedepends, checkdepends, optdepends, conflicts, provides, replaces, cksums, md5sums, sha1sums, sha224sums, sha256sums, sha384sums, sha512sums, b2sums.

Thanks for the detailed issue. The lexers here are copied over from https://github.com/orbitalquark/scintillua, though, so could you recreate this issue there?
