Remove the old Tags scripts that used it

where

[dgrammatiko]

@brianteeman I guess my comment is confusing, I mean there are 2 files (build/media_source/legacy/js/ajax-chosen.es5.js, build/media_source/legacy/js/joomla-chosen.es5.js) that depend on chosen and these are removed. Joomla 4+ doesn't use anywhere chosen thus chosen and the 2 files are removed. Also cleaned up any scripts that had chosen references

[brianteeman]

I assumed you referred to \build\media_source\system\js\fields\tag.es5.js which appears to use chosen and is not touched by this PR

I assumed you referred to \build\media_source\system\js\fields\tag.es5.js

That's the other part of the J3 tags that obviously I missed! Thanks
