Ensure plugin triggers warnings

[nephix]

Version info:

VERSION INFO:

Artillery Core: 2.0.0-16
Artillery Pro:  not installed (https://artillery.io/product)

Node.js: v16.15.0
OS:      darwin

When my artillery file contains:

config:
  plugins:
    ensure: {}

I expected to see this happen:

I don't see a warning in the console, because according to https://docs-nine-inky.vercel.app/docs/guides/guides/test-script-reference#ensure---slo-checks it's a built in plugin

Instead, this happened:

WARNING: Could not load plugin: ensure warn
WARNING: Plugin ensure specified but module artillery-plugin-ensure could not be found (MODULE_NOT_FOUND) warn
Phase started: unnamed (index: 0, duration: 20s) 20:11:52(+0000)

[2] WARNING: Could not load plugin: ensure warn
