fix: support undefined app.config `nuxtIcon`

[pixelastronauts]

Resolves #100

Problem

While accessing properties of nuxtIcon, the application would throw a TypeError if nuxtIcon was undefined.

Solution

Added optional chaining (?.) to safely access the nested properties of nuxtIcon.

Changes

• Implemented optional chaining to check the existence of nuxtIcon before trying to access its aliases property.
• This resolves the error: "TypeError: Cannot read properties of undefined (reading 'aliases')".

PR Summary

• Enhancement in Icon.vue Conditional Check The code in this file was updated to perform checks more efficiently when looking for specific properties in the appConfig.nuxtIcon object. This updated approach helps in ensuring these properties exist before trying to access them, preventing possible errors which could occur if certain properties are unavailable.

I've had this problem too and I think you're right.

Thanks, going to merge this as it's blocking me as well.

Edit: Turns out I can't publish releases for nuxt-icon so will need to wait for @Atinux or someone else to bump
