Progressbar in Svelte version does not show progress value

[space-nuko]

Describe the bug

The Progressbar component in the Svelte version doesn't update correctly. This is because the style applied to the element has an incorrect syntax

framework7/src/svelte/components/progressbar.svelte

Lines 29 to 32 in 09ef46f

	$: transformStyle = {
	transform: progress ? `translate3d(${-100 + progress}%, 0, 0)` : '',
	WebkitTransform: progress ? `translate3d(${-100 + progress}%, 0, 0)` : '',
	};

framework7/src/svelte/components/progressbar.svelte

Line 36 in 09ef46f

<span style={transformStyle} />

The style prop passed to the span has to be a string, not a JavaScript object

To Reproduce

Steps to reproduce the behavior:

1. Instantiate Progressbar
2. Set progress to a number

Expected behavior

Bar should display progress value

Actual Behavior

There is no progress update. In the devtools the style has become [object Object]

<span class="progressbar" data-progress="20"><span style="[object Object]"></span></span>
