Added new reviewer for Turkish translation (#2831)

Hello, I would like to support the translation of Rust into Turkish in
order to promote it in Turkey. As I saw in the previous PRs, we need to
add our own name here, so I am opening a PR in this regard. I hope it
will have a positive outcome (I know I opened the PR with the wrong
name, I'm sorry).
