[Tests] Fix index compatibility checks for AArch64

[jozala]

This is required to follow the same logic as for filtering supported versions in BwC:

elasticsearch/build-tools-internal/src/main/java/org/elasticsearch/gradle/internal/BwcVersions.java

Lines 294 to 306 in c5d3799

	private List<Version> filterSupportedVersions(List<Version> wireCompat) {
	Predicate<Version> supported = v -> true;
	if (Architecture.current() == Architecture.AARCH64) {
	final String version;
	if (ElasticsearchDistribution.CURRENT_PLATFORM.equals(ElasticsearchDistribution.Platform.DARWIN)) {
	version = "7.16.0";
	} else {
	version = "7.12.0"; // linux shipped earlier for aarch64
	}
	supported = v -> v.onOrAfter(version);
	}
	return wireCompat.stream().filter(supported).collect(Collectors.toList());
	}

AArch64 distro wasn't supported before 7.16 on Mac and before 7.12 on Linux.

This fixes the failing test on CI for AArch64 OSes.

Nice!. I wonder how come we only have detected that? 🤔
