bug: (vue) all TypeScript types missing from ion-* components since 8.4.3

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

Since @ionic/vue 8.4.3, all TypeScript information seems to be missing from components.

For example, when trying to get the possible values of size prop for IonTitle, it no longer returns detailed type information

Expected Behavior

As in @inoic/vue 8.4.2, TypeScript information is available to the IDE

Steps to Reproduce

1. Create new ionic vue project using ionic cli
2. attempt to get VS Code to use type information by using Ctrl + Space for the value of a Ionic component prop
3. No type information is available
