chore: unbundled esm (#8613)
- remove esm bundle step - introduce generated version.js because we can no longer use replace because we don't bundle esm - remove register hook, cjs compiler output and cjs runtime - keep umd compiler version for prettier/eslint/browser but without sourcemaps - move devdependencies to dependencies where necessary - various cleanup --------- Co-authored-by: Ben McCann <322311+benmccann@users.noreply.github.com> Co-authored-by: gtmnayan <50981692+gtm-nayan@users.noreply.github.com>pull/8628/head
