- Fixes collection and tab descriptions not having a bottom padding:
- Deprecates `description` on tabs config in favour of
`admin.description` but supports both
- Adds test to make sure `admin.description` renders with static string
and function too for tabs
Improves the admin e2e test splitting by grouping them by type with
semantic names as opposed to numerically. This will provide much needed
clarity to exactly _where_ new admin tests should be written and help to
quickly distinguish the areas of failure within the CI overview.
