bug: Vue IonTabBar missing slot prop type

[tdekoning]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v8.x

Current Behavior

In a Vue application with a strict templates vue-tsc preset (that disallows undefined properties to be set), using the IonTabBar with a named slot (for example slot="bottom") leads to a TypeScript error.

This is due to the fact that vue-tsc doesn't recognise a slot prop.

Expected Behavior

I expect the component definition to include the slot property.

Steps to Reproduce

In a vue project with vue-tsc's configuration set like so (part of tsconfig.json)

"vueCompilerOptions": {
	"strictTemplates": true
}

Add this to any vue component's template:

<IonTabBar slot="bottom">
	<IonTabButton
		tab="tab-home"
		href="/tabs/tab-home"
	>
		<p>Home</p>
	</IonTabButton>
</IonTabBar>
