docs: add get_ui_elements to the game_manage rollup inventory (#481) (#485)

PR #481 added the get_ui_elements op (runtime UI inspection) and updated
docs/TOOLS.md, but the game_manage rollup row in the skill inventory
table was missed. Add it so the two stay in sync. Follow-up item from
#484.

Docs only.
