Alt text bug

[PeterBowater]

Description

Describe the issue that you're seeing.

Referencing: #1545

You are unable to set an alt text of just '', to get an 'empty' alt text I have to user alt: ' ' as the attribute (i.e. with a space).

Additionally, the thumbnail images do not have an alt text attribute at all -ideally this should be definable, but most likely should just be set to "".

Thank you !

Steps to reproduce

See attached code.

JS code that you use to initialize lightGallery.

	const dynamicEl = images.map((value) => ({
		src: value.data.original.url,
		thumb: value.data.thumb.url,
		alt: ' ',
	}));

useEffect(() => {
			const inlineGallery = lightGallery(lgContainer.current, {
				container: lgContainer.current,
				dynamic: true,
				hash: false,
				plugins: [lgZoom, lgThumbnail],
				closable: false,
				showMaximizeIcon: true,
				appendSubHtmlTo: '.lg-item',
				slideDelay: 400,
				dynamicEl,
				preload: 1,
				download: false,
			});

			inlineGallery.openGallery();
		}
	}, []);

Environment

• Browser and version - all
• OS - all
• lightGallery version - 2.7.1
