Description: This generic notice was added as a preventive measure, considering that we cannot auto-identify if extensions are incompatible, except for payment extensions. However, this might prevent users from adopting the block-based experience, even if they aren't using incompatible extensions, and extension developers had plenty of time to enable the incompatibility flag. The block-based experience has been the default since November. Therefore, we think it's time to remove the generic notice.

Acceptance criteria:

• Remove generic notice from the Cart page/template when the store doesn't have incompatible extensions
• Remove generic notice from the Checkout page/template when the store doesn't have incompatible extensions
