LGTM, nothing in terms of the code itself but a few things before merging:

• For the "Edit dataset's metadata & sharing options" button, can we make it title case just to match the letter case on the other surrounding buttons.

• Because you're overriding a template and not using the ckan_extends the settings for plugins list needs to be updated so that the smdh plugin is second to the last plugin in the list (with a comment explaining why the plugin needs to be at the end of the list).
  This is because template extension is co-operative and relies on each plugin having the tag ckan_extends. Not that it would affect anything right now but future proofing so that if a plugin needs to extend this template there won't be any confusion.
  This setting is specified in multiple locations using env files in the ckan-smdh (under contrib/docker-ckan), and ckan-smdh-prod repo.
