Problem/Motivation
In #1975064: Add more granular block content permissions we added new permissions for block content module
However the hook help entry still references the old administer blocks permission
Steps to reproduce
Creating and managing block types
Users with the Administer blocks permission can create and edit block types with fields and display settings, from the Block types page under the Structure menu. For more information about managing fields and display settings, see the Field UI module help and Field module help.
Creating content blocks
Users with the Administer blocks permission can create, edit, and delete content blocks of each defined block type, from the Content blocks page. After creating a block, place it in a region from the Block layout page, just like blocks provided by other modules.
Proposed resolution
Update the help text to be more appropriate to the new permissions
