Alert for content editors on incorrect block usage (1)

[shirin27]

From vg-volvotrucks-us-rd created by cogniSyb: Netcentric/vg-volvotrucks-us-rd#274

We should display an alert on environments when the content editor adds a v2 block on the page that is not a v2-redesign page. This will allow incorrect use of a component to be spotted more quickly and reduce errors and questions in the future.

• [x] Will we also add an alert when a non-redesign block is used on a redesign page?

Requirements

• Check whether AEM Sidekick is open, execute the script
• If the user is on a redesign page
  • Check whether a non-redesign block is present on a page (a block that doesn’t start with v2-)
  • If the block is on the allowlist, we ignore it
• If the user is on a regular page
  • Check whether a v2 block is present on a page (a block that starts with v2-)
  • If the block is on the allowlist, we ignore it
• Explain what the problem is and which block is used that is 'in violation'
• The modal can be closed with a button

Allowed blocks

On both redesign pages and non-redesign pages, the following blocks are allowed:

• Embed
• Footer
• Fragment
• Header
• Iframe
• Modal
