(core) Fix staging test and tweak template line height

Summary:
Staging tests were using an organization named Test Grist,
while local was using one named test-grist. Both are now
named Test Grist, which should help keep things more consistent
between local and deployment test runs.

The inherited line height of template docs in icon view was
different on Windows, cutting off part of the last line of the
description. The description line height should now be fixed
to a reasonable value.

Test Plan: Manually tested CSS fix on a Windows machine.
