add linux-aarch64 GitHub Action coverage

Using https://github.com/actions/partner-runner-images/blob/main/images/arm-ubuntu-24-image.md

Oh cool, I didn't know about those images. Seems that we pick the wrong binary for arm though

/opt/hostedtoolcache/cmake/3.31.5/arm64/cmake-3.31.5-linux-x86_64/bin/cmake

probably needs adding to

actions-setup-cmake/src/version.ts

Lines 59 to 72 in 09fd9b0

	function extractArchFrom(filename: string): string {
	if (filename.match(/x86_64/)) {
	return 'x86_64';
	} else if (filename.match(/x64/)) {
	return 'x86_64';
	} else if (filename.match(/universal/)) {
	return 'x86_64';
	} else if (filename.match(/x86/)) {
	return 'x86';
	} else if (filename.match(/i386/)) {
	return 'x86';
	} else {
	return '';
	}

and to here

actions-setup-cmake/src/index.ts

Line 19 in 09fd9b0

const arch_candidates = use_32bits ? ['x86'] : ['x86_64', 'x86'];
