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 -->
Plugins were not being loaded by vitest executor when calling
`startVitest` when using a vite config file with a custom name.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
Correctly load the plugins found in the resolved config file, regardless
of the config file name
