Wiki pages list (/wikis/pages): "New page" button missing for Group wikis but present for Project wikis

Summary

On the /wikis/pages list page, Project wikis display a "New page" button, allowing users to create a new wiki page directly from the pages list. However, this button is absent for Group wikis.

To create a new page in a Group wiki, a user must:

1. Navigate into an existing wiki page
2. Open the dropdown in the top right
3. Select New page

This is an inconsistent experience between Project and Group wikis, and the workaround is non-obvious — particularly for users who are not yet familiar with the wiki interface.

Steps to reproduce

1. Navigate to a Project wiki's pages list (/wikis/pages)
   • Observe: a "New page" button is visible
     • 
2. Navigate to a Group wiki's pages list (/wikis/pages)
   • Observe: no "New page" button is present
     • 

Impact

• Users of Group wikis have no direct way to create a new page from the pages list, unlike Project wiki users
• The workaround (entering an existing page → top-right dropdown → New page) is unintuitive and easy to miss
• This inconsistency may cause confusion, especially for users who switch between Project and Group wikis

Questions for consideration

• Should the "New page" button be added to the Group wiki /wikis/pages page for consistency with Project wikis?
• Is the absence of this button for Group wikis intentional? If so, what is the rationale?

Implementation considerations

• This appears to be primarily a frontend change — adding the "New page" button to the Group wiki pages list, mirroring the existing behaviour for Project wikis
