Update supported version for fixing the bug of noop_update_total metric cannot be updated by bulk API

[gaobinlong]

Description

Part of #11485, after the original PR has been backported to 2.x branch, we need to update the supported version to 2.12.0 so that the backward compatibility checks can cover the change.

This PR needs to backport to 2.x because the supported version in 2.x branch is also 3.0.0(it's done by the bot).
