v2.1.3 seems to break @vitest/web-worker path in NX Monorepos

[K3TH3R]

Describe the bug

I've been upgrading our dependencies to the most recent versions lately and I've started receiving the following error in our NX Monorepo related to @vitest/web-worker that is breaking all of our unit tests:

Error: Failed to load url /Users/kether/frontend/node_modules/@vitest/web-worker/dist/index.js (resolved id: /Users/kether/frontend/node_modules/@vitest/web-worker/dist/index.js). Does the file exist?

What's particularly weird is that the file is there as expected:

The unit tests run fine up to and including 2.1.2. But as soon as I upgrade to 2.1.3 or above, I start getting the error which breaks our test suites. If I leave [email protected], I can continue to upgrade @vitest/web-worker up to 2.2.0-beta.1 with the unit tests continuing to run as expected.

Reproduction

1. git clone [email protected]:K3TH3R/ts-issue-starter-template.git vitest-path-issue
2. cd vitest-path-issue && git checkout vitest-2.1.2 && yarn install
3. yarn app1:test -> everything runs as expected
4. git checkout vitest-2.1.3 && rm -rf node_modules && yarn install
5. yarn app1:test -> fails with the @vitest/web-worker error

The only thing that has changed between these two branches is the Vitest dependency versions.
