Fix: Remove user-data-dir usage in tests on mv3 builds (#24696)

## **Description**

"The user data directory contains profile data such as history,
bookmarks, and cookies, as well as other per-installation local state."

We are using the `user-data-dir` command and unnecessarily caching such
data in the `test-artefacts/` directory. With local testing, and
seemingly with test run as part of the same job on CI, it can be seen
that this cached data has persistence between test runs, and can thereby
cause flakiness. Locally, it seems that old builds of the extension can
be cached. On CI, it seems that things like our fetch cache can be
persisted between browser sessions.

I do not believe this is actually used for any purpose, and we can
reduce flakiness by removing it.
