[ci] increase timeout for performance pipeline step to 90 min (#175044)

Recently we have few more journeys added and sometimes overall run time
is over 1h and step is aborted because of 60 min timeout.

Increasing timeout to 90 min to avoid re-runs and in the meantime I will
start looking into how to optimise & decrease the journeys runtime.
