ZTS: CodeQL Action v3 update

Switch from v2 to v3 CodeQL Actions. The v2 actions will no longer
be supported as of Dec '24 so we need to move to v3. According to
the release notes they should be functionally equivalent.

    Note that the only difference between v2 and v3 of the CodeQL
    Action is the node version they support, ... For example 3.22.11
    was the first v3 release and is functionally identical to 2.22.11.
