refactor: remove course taxonomy permissions

[bra-i-am]

Removes the manage_taxonomies permission from the UI as decided in openedx/openedx-authz#309

The course admin can manage tags, but can't manage taxonomy (it is not related to a course role); the content tagging will have its own permissions.

Closes openedx/openedx-authz#309

Changes

• Removed MANAGE_COURSE_TAXONOMIES from the CONTENT_COURSE_PERMISSIONS enum
• Removed the "Manage taxonomies" entry from the permissions list rendered in the UI
• Removed MANAGE_COURSE_TAXONOMIES from the course_admin role definition
• Updated the "Tags & taxonomies" resource group label to "Tags"

Applied to both authz-module/constants.ts and roles-permissions/course/constants.ts.

Screenshot

Pending

The permission also needs to be removed from openedx-authz (constant definition and role policy assignment).
