Enhancement: Use Nuxt Icon module for SVG's instead of inlined SVG's

[luc122c]

I think it would tidy up the source code a lot to use the Nuxt Icon module where possible. For example, to replace this icon. From my understanding, they would be rendered to HTML (SVG) as part of the build process, so the end result shouldn't change?

We can use the UIcon component from https://ui.nuxt.com actually to improve this
