Summary of Changes

Recent changes in BS have some sharing code from Alert and Modal for other components. Since Joomla is not distributing a monolith for the JS the build script had to be informed.

EDIT: What happen: The Alert and Modal are now using common code for the close button that lives in the js/src/util/... https://github.com/twbs/bootstrap/blob/main/js/src/util/component-functions.js
as it can be clearly seen in https://github.com/twbs/bootstrap/blob/d8999dd5666336dcf6976cc65bc0d562a4baec5a/js/src/alert.js#L11 and https://github.com/twbs/bootstrap/blob/d8999dd5666336dcf6976cc65bc0d562a4baec5a/js/src/modal.js#L23
To prevent such changes breaking the builds, the build script will automatically add any files in the src/js/dom and src/js/util to the external scripts and create a chunk with all of them ./dom.js. This should be future proof as it doesn't have any of these imports hardcoded...

Testing Instructions

• A broken example that you can test is #36169
• But also a simple check before and after on the network waterfall is enough:
• • Before, double entries for alert+modal

• • After, no double entries
