[web] <img> tag attributes are ignored during HTML export

[amigo70707]

When exporting HTML, react-native-enriched-html ignores <img> attributes such as the image link (src), width, and height. Only the bare <img /> tag gets exported.

Hi @amigo70707 !
Thanks for creating this issue. To clear things up, this behavior is expected. The web's sanitization is configurable via sanitizationConfig. It just wasn't set properly in the provided example app. We'll fix it shortly.

You can find details about sanitizationConfig in the WEB.md documentation in the repo's root.
