fix existing load testing script

[thecristen]

Scope

No ticket, I noticed the current load testing script added in #1891 didn't actually work 🫠

Implementation

• First was a mismatch between our Playwright version and the version associated with Artillery, our load testing library. Updating them to these versions worked.
  • Also updated axios because security 🔒
• The references to the named functions were formatted incorrectly, so I updated them to reflect the correct values
  • One test was for a feature which no longer exists, so I removed that one

How to test

• Install/update the dependencies (npm install --ignore-scripts from the root folder)
• Run the load tests and note it runs to completion (can use below or substitute target of choice):

npx artillery run ./integration/load_tests/all-scenarios.yml --target https://dev-blue.mbtace.com
