YQL-20095: Enable modernize-use-override

2026-01-13T14:55:02Z

The check `modernize-use-override` is useful as it: 1. Removes redundant `override` when it is used with a `final`. 2. Removes redundant `virtual` or replace it with a `override`. So it is more clean for a reader, that overriding happens. It is enabled not out of order, as it is just an alias to `cppcoreguidelines-explicit-virtual-functions`. I also decided to switch a strategy of enabling checks. Now I will enable only a single rule with a single PR and prefer rules with a non-breaking autofix. In the new year with new linter checks! 🎄 commit_hash:e6e233baa90b31e5f65e11837546690c47f71ab5
