[Tarantool-patches] [PATCH luajit] ci: update action/checkout to v3

[Sergey Kaplun]

Node.js 12 is used by action/checkout v2. It will be deprecated soon,
according to our CI warnings. So update action/checkout to v3.

Branch: https://github.com/tarantool/luajit/tree/skaplun/gh-noticket-actions-v3

Side note: M1 CI feels bad for now (unrelated to the patch), but
warnings are gone :).
