<!-- 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 -->
```
[webpack-dev-server] WARNING
  ⚠ DefinePlugin:
  │ Conflicting values for 'process.env.NODE_ENV' ("'development'" !== "\"development\"")
```

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
`process.env.NODE_ENV` should resolve to `'development'` and not a
quoted value: `"'development'"`

<!-- Please link the issue being fixed so it gets closed when this is
