Hi, Alexander,

thanks for the patch! LGTM with minor comment

Sergey

The main idea behind the switch is to have less of our own
infrastructure to support, see tarantool/tarantool#13278 for details.

Drafted by an LLM, conducted and corrected by the commit author.

after the patch we will use github runners and it is worth set a timeout for jobs,

otherwise we might run out of time on the runners (AFAIK it is limited there).
