<!-- 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 -->
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.

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
Fixes #28040 (port portion)
