[clang-tidy] Add vbvictor to list of maintainers (#167407)

I've been actively contributing to the `clang-tidy` project this year
and was reviewing patches practically daily for the past half a year.
[As per LLVM
policy](https://llvm.org/docs/DeveloperPolicy.html#maintainers), I
believe I've successfully carried out maintainer responsibilities, thus
I volunteer to become one.
I'm looking forward to staying engaged with LLVM community, help
newcomers and develop `clang-tidy` as well as other LLVM projects.
