Missing translation keys for the Workspace Application in the Administration page

In the workspace administration section there are no translation keys for the "Workspace" option (under the "Configuration" section) and for the "Workspace Users" option (under the "Users and Groups" section).

Also, in the page "XWiki.ManageWorkspace" the 3 options from the "Membership Type" section have no corresponding translation keys.

In the page "XWiki.WorkspaceUsers" the translation for "Message" appears as "platform.workspace.inviteMessageLabel" when switching to French because the key is not yet added to "WorkspaceManager.Translations".
