fix(assets): add the missing await to getHTMLAttributes

[sumimakito]

Changes

This pull request adds the missing await to properly use values returned by getHTMLAttribute in image services. It fixes an issue where HTML attributes do not render if getHTMLAttributes in an image service returns a Promise.

Minimum repro for this issue: StackBlitz (You can see that the custom HTML attributes are not rendered in the HTML if getHTMLAttribute returns a Promise instead a plain object)

Definition for getHTMLAttribute:

astro/packages/astro/src/assets/services/service.ts

Lines 41 to 50 in 30de324

	/**
	* Return any additional HTML attributes separate from `src` that your service requires to show the image properly.
	*
	* For example, you might want to return the `width` and `height` to avoid CLS, or a particular `class` or `style`.
	* In most cases, you'll want to return directly what your user supplied you, minus the attributes that were used to generate the image.
	*/
	getHTMLAttributes?: (
	options: ImageTransform,
	imageConfig: ImageConfig<T>
	) => Record<string, any> | Promise<Record<string, any>>;

Testing

No tests were added as this is a one-line fix. It should have no impact if getHTMLAttributes returns a non-Promise.

Docs

No docs were needed as this fix does not change the expected behavior.
