feat: optionally store artifacts after script in run job

[loderunner]

SEMVER Update Type:

• [ ] Major
• [x] Minor
• [ ] Patch

Description:

• add a parameter to upload a path to artifacts after running a script in the run job

Motivation:

Running a script often produces new files to be stored as artifacts. For example, many front-end projects use a bundler such as Webpack or Vite, and TypeScript projects need to be transpiled to JavaScript. These tools are often controlled with a build, compile or webpack script.

After this step, the produced files often need to be persisted somewhere, and artifacts seems like a good place.
