‘Multiple Post Thumbnails’ – Compatibility with WP 6.0.2?

@dwpro I’ve posted an issue over on the Github repo for the plugin, hopefully it will prompt a little compatibility update: https://github.com/voceconnect/multi-post-thumbnails/issues/153

From my own use I don’t seem to encounter any errors with the plugin under WP6+ (have you had any issues? Any PHP8+ issues?), so I think it just needs a small update to mark as compatible with WP6.1.

@dwpro I’ve just created a pull request with an update to the Readme file to say that it works with the current version of WordPress. Hopefully it will give a nudge to the developer to make that little update.
