Primary Drop Button style update

Rerolling patch #53

Previous patch failed to apply, updated it for 11.x.

Is this issue still relevant? Should it be replaced by 📌 Refactor Claro's dropbutton stylesheet Needs review ?

@andy-blum, Guiu Rocafort Ferrer and I worked during DrupalCon Lille Contribution Day on this and created a custom module for testing if the patch fixes the issue as the workbench moderation module is not compatible with 11.x yet, the buttons are there but we are not sure if we are missing any class as it is not working as per the design in Figma. If this module works then we can move this to test in Claro.

Apologize, may be a case of the Mondays but could the issue summary be updated or title updated to show what the problem is?

Working on this issue as a part of Claro Contribution Day.

Could not work on it. So removing the tag ClaroContributionDay2023
