fix(benches): bench sequentially

[yash-atreya]

Motivation

Currently, the benchmarks run in parallel using the same forge bin on the same machine. This leads to incorrect / slow results due to resource contention.

Solution

• Run benches sequentially per project
• Fix CI workflow to run sequentially as well since it's run on a self-hosted runner.

PR Checklist

• Added Tests
• Added Documentation
• Breaking changes
