Replace rimraf with native Node.js fs.promises

Description

Currently, we use rimraf in the following location:

We should replace this dependency for the following reasons:

• Environment: These tests only run on Ubuntu, so we do not strictly need to leverage a package designed for cross-platform directory deletion.
• Security: rimraf currently has a vulnerability due to its dependency on glob 10.4.5.

Proposed Solution

A simpler and more secure solution is to use Node's native fs promise to delete the directory.
