fix(geo): respect tooltip.show=false in geo region tooltip config (Fixes #20232)

[waterWang]

Problem

When geo.tooltip.show is set to false, the tooltip still shows when hovering over geo regions because resetTooltipForRegion unconditionally sets the tooltip config on each region element.

Root Cause

In src/component/helper/MapDraw.ts, the resetTooltipForRegion function always calls graphic.setTooltipConfig() with the region's tooltip option, without checking whether show: false is explicitly set.

Fix

Added a guard in resetTooltipForRegion to check if the tooltip option has show: false before setting the tooltip config. If the tooltip is explicitly disabled, the function returns early without setting the config, so the tooltip component will not show a tooltip for that region.
