Single file component <template> section

In this part, we will create the <template> section of the single file component. Follow these instructions to create the component correctly:

1. In the src/views folder, create a new file called NotFound.vue and open it.

2. Create a VsRow component and inside of it create four VsCol components. All of those components will have the attribute vs-w defined as 12 and class as text-center:

<vs-row>
  <vs-col vs-w="12" class="text-center">
  <!-- Icon -->
  </vs-col>
  <vs-col vs-w="12" class="text-center">
  <!-- Title -->
  </vs-col>
  <vs-col vs-w="12" class="text-center">
  <!-- Text -->
  </vs-col>
  <vs-col vs-w="12" class="text-center">
  <!-- Button -->
  </vs-col>
</vs-row>

3. On the first VsCol component, we will add a VsIcon component, and set the attribute icon as sentiment_dissatisfied...
