Artillery Fake Data Plugin

The `artillery-plugin-fake-data` package enhances Artillery load testing by enabling easy generation of randomized test data, primarily leveraging the `falso` library. This plugin allows developers to embed fake data generation directly into their Artillery YAML test scripts using a simple `$functionName()` syntax, or programmatically within JavaScript `beforeRequest`, `afterResponse`, and `function` hooks via `context.vars.$functionName()`. Currently at version `1.21.0`, it is marked as 'experimental' and under active development, indicating a potentially frequent release cadence and possible breaking changes. Its key differentiator is the tight integration with Artillery's configuration, offering a streamlined approach to dynamic data for HTTP-based tests, contrasting with `artillery-plugin-faker` which provides the full `faker.js` API for more complex, locale-specific, or custom data generation needs.
