Merged PR 452: Automate the benchmark process

## Summary
This pull request integrates full automation of the PrimAITE benchmarking process into our Azure DevOps pipeline, enhancing consistency and minimizing manual effort.

#### Key Changes:

1.  **Pipeline Automation**: Configured to trigger on commits to `dev` and `release` branches, with scheduled runs during off-peak hours.

2.  **Error Handling Improvements**: The pipeline is set to fail on any Python execution errors, ensuring immediate identification of issues.

3.  **Artifact Publishing**: Benchmark results are now automatically compressed and published as artifacts, facilitating easy access and analysis.

## Test process
Tested the pipeline runs from end-to-end and produces a working benchmark report: https://dev.azure.com/ma-dev-uk/PrimAITE/_build/results?buildId=5280&view=results
