CI: Initial Release test workflow (#1749)

<!-- .github/pull_request_template.md -->

## Description
Created `Release Test Workflow` that for now executes load tests. It's
being triggered manually and on a PR to `main`.
NOTE: Release workflow is not in required checks because it contains new
and unstable tests. We will need to watch it ourselves.

The `Load Test` workflow is being called from the `Release Test
Workflow` and also manually on demand.
Limited load test duration to 60 minutes.
