Updated example TodoApp to script setup

[hdJerry]

I noticed a few things which I am not sure if it was delibrate

• I updated the todo app in the examples to use script setup
• updated the test to use describe and it just like all the tests on the project
• updated the comment on the test in examples
• added some types

I noticed I couldn't run the test until I included the path to where the todo app test is, like so:

include: ['tests/**/*.spec.ts', 'examples/**/*.spec.js'],
