fix: show the existing field meta when editing a template fields (#1323)

Fixes #1259. I literally just used the exact same line of code than from
the document page so it is consistent.

The bug is extremely frustrating because if you make change to the
fields meta on the template and refresh the page, you can't see field
meta (label, default value, required), and neither do your co-workers.

Of course, I tested the change and it now displays correctly the
existing field meta on the template page.
