someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they

## Current Behavior
<!-- This is the behavior we have today -->
`withNx` from `@nx/rspack` is not reflective of what `@nx/webpack` does.
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
Bring `withNx` in line with `@nx/webpack`

## Current Behavior
<!-- This is the behavior we have today -->
Port is not respected from `rspack.config.[jt]s` and needs to be
explicitly set in `project.json` options.
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
Port should be configurable via config, options, etc.
