The removal of decorateButtons from the exports will break the existing code in scripts/scripts.js, which imports and calls this function on lines 5 and 85. This PR is incomplete as it only updates aem.js but does not update the dependent scripts.js file.

To complete this migration to aem.js v3.0.0, you must also update scripts/scripts.js to:

1. Remove decorateButtons from the import statement on line 5
2. Remove the call to decorateButtons(main) on line 85

According to the aem.js v3.0.0 breaking changes, button decoration functionality has been removed from the core library.
