fix(vite): load the correct config file from @nx/vite:test executor (#27514)

This PR ensures that we pass Vite config file to the programmatic
`startTest` API from Vitest. It fixes the issue with plugins not loading
as well as other issues with the config file not being used.

This mainly affects a custom `configFile` option being passed to the
executor. The previous fix to additionally load in `plugins` via
overrides is causing plugins to load twice when the Vite config file is
picked up by Vitest (e.g. #27500).

## Current Behavior
<!-- This is the behavior we have today -->

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

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

Fixes #27500, #22001
