TabView: previousicon slot doesn't work

[yellowgiraffe]

Bug description

I have encountered an issue with previousicon slot (link to docs) for TabView component. While the nexticon slot successfully replaces the icon with a different type and changes the color to purple, the previousicon slot remains unchaged.

Example: StackBlitz Example

---

Upon further investigation, I noticed that the interface TabViewSlots has a slot name - previousicon. In contrary the source code of the TabView component, available on GitHub (line 16), indeed defines the previcon slot.

So when I changed the slot from <template #previousicon></template> to <template #previcon></template> it updated the icon.

Example: StackBlitz Example

However, this modification leads to a TypeScript error, stating "Propterty 'previcon' does not exist on type 'TabViewSlots. ts(2339)'"

Therefore, adjusting the name in the TabViewSlots interface or changing the name of the slot in TabView.vue would resolve the icon replacement issue.
