As a Dev - I want to change the CI workflow on the plugins repository to publish a beta version only on comment

[abrl91]

Related issue: #7441

Current implementation

A new plugin beta version is published on every new and synchronized pull request.

New requirement

On every comment on the PR a new beta version of a plugin will be published with the same format that we have in the current implementation: <version in package.json>-beta.pr-<pr number>.<commit short sha (7 chars)>
i.e. for pr # 7441 1.2.1-beta.pr-7441.979a26c

• get affected plugins
• execute a publish dry run for every plugin that was changed and check if the current version can be published
• publish

@abrl91 ⚠️
Version bump validation must happen on PR for every commit as we don't want to merge a PR with changes on a plugin that has not been version bumped otherwise we will have a failing publish pipeline in master
