App router migration google tag manager script (#1117)

* Add basic Root Layout * Add metadata * Add reference included by next * Add comment to explain the default meta tags * Add public testing page to check the migration * Remove non required file * Add google tag manager to root layout * Change strategy as worker is experimental and is not including the script * Move gtm to body as next is including it in head properly * Add comment to tackle in the future * Move gtm script from _document to _app
