fix(ButtonGroup/AvatarGroup): allow v-for

[discountedcookie]

<UButtonGroup size="md">
  <UButton
    v-for="type in ['One', 'Two', 'Three']"
    :key="type"
    :label="type"
    color="white"
  />
</UButtonGroup>

Currently this fails, since the first child of ButtonGroup will be a Fragment.

@ciaasteczkowy Did you manage to make this work? Just tested and it doesn't ever resolves this condition: children[0].type === Symbol.for('v-fgt').

The only way I've managed to make this work is to transform the condition to typeof children[0].type === 'symbol'.

Just pushed to your PR, with the same fix on AvatarGroup. Let me know if this works for you!

You're right. I only made a change directly in the installed package to see if it works.

Thanks for finding another place where it can be fixed!
