Fix unit test warnings - Githubissues

Fixes

Related to #5171 by @obulat

Description

This PR introduces multiple improvements to the unit tests to eliminate warnings and produce cleaner output.

Removed the custom render-suspended function we used to override nuxt/test-utils. Since we now consistently use script setup instead of defineComponent, the default render-suspended function works seamlessly.
Updated component props. Several components' props have changed, so I updated them in tests.
Added ESLint Rule for props with defaults: "vue/no-required-prop-with-default" ESLint rule marks a prop optional if this prop has a default value. This helped fix a couple of warnings and components ( for example,VHomeLink, VLogoloader).
Updated issue Link: Corrected the issue link to point to the tracker for unit test fixes following the migration to Nuxt 3.
Addressed prop fall-through in complex components: When a component is complex, such as a VTag that :is="VButton" that :is="VLink" (3 levels of nestedness), the prop does not always fall through, at least in the unit tests, so I added manual binding of the href to VButton if the component in VButton is a VLink.

Testing Instructions

Run the unit tests using ov just frontend/run test:unit. You should see much fewer warnings.
