Bring periodic perf tests on GitHub back (#2037)

* test/fixtures: fix DeprecationWarning
* workflows/benchmarking: increase timeout
* test: switch pgbench to default(simple) query mode
* test/performance: ensure we don't have tables that we're creating
* workflows/pg_clients: remove unused env var
* workflows/benchmarking: change platform name
