<!-- 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 -->
When using Module Federation with an app that defines styles as a
separate entry point, HMR fails to update in the browser. Instead of
updating automatically, a warning is shown in the console related to a
missing chunk. A full-page reload is typically required, which is not
the intended behaviour.


## Expected Behavior
<!-- This is the behaviour we should expect with the changes in this PR
-->
HMR should work with styles as an entrypoint.

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
The default is for `runtimeChunk` is `config.optimization.runtimeChunk =
{name: 'runtime'}` it is _not_ the same as `single` but the naming will
be the same.

Fixes #9582
