Only check for document permissions when verifying entity actions for a document.

Description

Although I haven't been able to replicate the reported issue, I can see the proposed solution is sensible, as it allows us to by-pass complex logic for verifying document specific permissions, when we aren't working with a document.

So I've applied that here.

Testing

To verify, use a set up such as:

• Create a user in only the "Editors" group
• Add a document specific permission to a document that removes some permissions that the editor normally has.
• Verify when expanding the entity actions menu that the default editor permissions appear on documents without the document specific permission, but that the restricted set appears on those that have it defined
• Verify that default editor permissions appear on all entity action lists that aren't based on documents (e.g. media, members, dictionary).

Pull Request Overview

This PR fixes a bug where document-specific permissions were being checked for all entity types, not just documents. The fix ensures that complex document permission logic is only executed when the entity type is actually a document.

Key Changes

• Added entity type check before evaluating document permissions
• Simplified the code structure by removing an unnecessary conditional block
• Fixed comment capitalization for consistency
