Fix button-or-div to allow button type to be changed

[joshhanley]

The scenario

Currently if you want to use a badge as a submit button, the button's type is set to button even if you pass in type="submit".

<flux:badge color="cyan" as="button" type="submit">Submit button</flux:badge>

The problem

The badge component is wrapped in the button-or-div component and the attributes are being correctly forwarded to it.

But it turns out that the type on the button in the button-or-div component is hard coded, so can't be overridden with attributes.

<button type="button" {{ $attributes }}>

The solution

Change button-or-div button so that the type can be merged in through attributes.

<button {{ $attributes->merge(['type' => 'button']) }}>
