[CHORE] Ensure tool versions get saved as artifacts available to the rendered charts

[darcyclarke]

📋 Description

Currently, the tooling versions will get logged in the workflow run but those logs are ephemeral & the charts are intended to save the data/state overtime (so its important to store the versions of the tools we've benchmarked as they'll change over time).

📂 Category

🎌 Scope of Work

.github/workflows/benchmark.yaml & scripts/generate-chart.js
