Migration from unified i18n package to independant

Since we begin to use changeset for independent releases, the i18n workflow doesn't fit anymore because

• we use one i18n package for all TUI.
• the translation version follows the package version. So with different versions per package, we can't match a translation version anymore.

In PR #3462, we separated the i18n workflow for each package in talend/ui that needs translation.

For further updates on translation, applications' code needs to be adapted.

Package.json

Locales packages need to be updated, as we don't have 1 package for tui now, but 4 packages.

> yarn remove @talend/locales-tui
> yarn add @talend/locales-tui-components @talend/locales-tui-containers @talend/locales-tui-forms @talend/locales-tui-datagrid

Feel free to remove the packages you don't need.
