remove request and upgrade artillery

[agnesgaroux]

What does this change?

Critical vulnerabilties: dependabot alerts
request has been deprecated, use fetch instead
upgrading artillery
using aws-sdk v3 to get secret value

How to test

Run the tests in ci? 😬
running locally I get

Test run id: tyy46_4w7re3tjh5macgbtxexw6gc5mwd3n_4fbw
Phase started: unnamed (index: 0, duration: 1s) 11:06:31(+0000)
Phase completed: unnamed (index: 0, duration: 1s) 11:06:32(+0000)

but then it hangs there with Warning: multiple batches of metrics for period 1741777590000 2025-03-12T11:06:30.000Z

How can we measure success?

smoke tests run in ci, fewer vulnerability alerts

Have we considered potential risks?

Limited as only testing
