Use latest stable plugin version (not dev) to generate screenshots from

Screenshots are made from released versions only

Running this workflow from an unpublished development release leads to 404s on all language packs

Description of the Change

Thats why we grab the latest release directly from wp.org, which makes sure the existing translations will match the loaded codebase.

Alternatives

We could instantly rewrite the version numbers in .php and .md file to match the latest stable version.
This would allow downloads.wordpress.org/translation to find and load the translation files. But it could be that parts of the plugin will not be translated or not be as accurate as on the last stable.

# Closes an undocumented problem with the new wp-playground/cli powered screenshot generator.

How to test the Change

Lets start the workflow and lets see if french UI, will be really french UI !
