[clang-tools-extra] [Docs][clang-tools-extra] Convert maintainers list to .rst format (PR #165171)

[Baranov Victor via cfe-commits]

https://github.com/vbvictor created https://github.com/llvm/llvm-project/pull/165171

[Clang maintainers list](https://github.com/llvm/llvm-project/blob/main/clang/Maintainers.rst) is already in `.rst` format, which gives nice visuals.
I think we should convert clang-tools-extra maintainers too to `.rst`.
