<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
<!-- This is the behavior we have today -->
`nxViteTsPaths` does not check if the mode is test and only filters the
`run-many` command based on whether Vite's config.command === serve.

Vitest will set `config.command` to serve, even for `test` targets.
It does set `mode = test` however.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
When `mode === test`, we do not invoke `nx run-many`

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
