We're going to add help content here and having a floating button would
make the button disappear when creating content for mobile phones.
I'm not sure having the link in the <header> tag is semantically
correct, but is consistent to what we did to create local targets in the
SDG content section.
Note we're changing the style of the link to create local targets so
it's consistent with the link to create budgets/groups/headings.
To make it more consistent with the rest of the Admin panel,
the CRUD for budget groups and headings has been changed
from the old "all-in-one" form to a separate form for each resource.
