chore: add prelerna-publish to beta releases

[rubencarvalho]

Description

We want beta release artifacts to be 1:1 with those in latest, so we need to add the prelerna-publish command which generates the custom-elements.json manifests and runs the script to verify the build artifacts.

Motivation and context

Without this, the manifests do not get published.

How has this been tested?

You can see the build artifacts of a beta test release here: https://www.npmjs.com/package/@spectrum-web-components/button/v/1.2.0-beta.3?activeTab=code

And you can see the action run here: https://github.com/adobe/spectrum-web-components/actions/runs/13309656501/job/37168759349?pr=5094
