run system-tests on pull requests

[cbeauchesne]

Description

• Run system-tests on PR (previously only on push on main)
• Optimize CI time
• Use idiomatic parameters for system-tests workflow

Motivation

#268 introduced a bug on main, if system-tests were executed on PR, this would have prevented the bug to reach main. It caused many rework to fix the issue.

CI on PR already last for more than 7mn (example). This job, with the parameter parametric_job_count last for ~5mn. so this new job want slow down the CI process.

(I restarted the sub-job get parameters to get a real duration value, as the runner is cached, the first run had to compute it, but next one will use the cache))
