Better shortcut action link styles when there's limited horizontal space

Re-rolled #26, for Drupal 10. As es6 files are no longer used in D10. Also popperjs has been updated to loadjs. Attached a patch and interdiff for same. Please review.

I will double check this issue

   I don't believe loadjs is needed anywhere in this fix so this doesn't need to be added as a dependency

   In other words, use code from shortcut.es6.js from the earlier Drupal 9 patch in this shortcut.js file. This is a copy of the transpiled JS, and Drupal 10 no longer transpiles its JS (hence no .es6.js + .js files)

Made changes as pointed out in #38, thanks!

There are issues found in #40 that have not been resolved in the meantime, is there a reason why you'd just ignore that update @Guru2023?
