This PR is a different approach compared to #3487.
Instead of checking whether we are in a test environment (specifically
in a Jest environment), I think we can just get rid of the check
entirely and use the virtualizer in all environments.
This will remove an unnecessary check for `process` being available and
gets rid of `process` entirely. It also fixes an issue that #3487 tries
to solve where `process` is available, but `process.env` is not.
Closes: #3487
