### What?
Although the following examples:
- `custom-components`
- `email`
- `multi-tenant`
were recently migrated to 3.0 - they were still using the latest `beta`
version instead of latest payload (i.e `3.0`)
Changes:
- Migrates `email` example project to `3.0` from `2.0`
- Replaces `inline-css` dependency with `juice` package instead.
- Replaces `Handlebars` dependency with `ejs` package instead.
Reason for replacing packages:
- Both `inline-css` & `Handlebars` had issues with Nextjs and its
Webpack bundling i.e does not support `require.extensions`.
- `ejs` & `juice` do not rely on `require.extensions`.
