Issue details

After the removal of the two deprecated implementations (JS and Java), it would be nice if we move all content from go/ folder into root.

Things to note:

1. There is a duplicate resource folder (go/utils/langfiles/resources/* - identical to - resources/*) where we have the same language files. The only instance using the go/utils/langfiles/resources is the .github/workflows/checkLang.yaml. We need to remove those files and update the workflow to use the resources/ ones.
2. This update will have an impact to all open PRs. So we need to coordinate before merging.

Target date: June 30
