lisp/ox-html.el: Add avif support for html export inline images 

* lisp/ox-html.el (org-html-inline-image-rules): Add AVIF image
support for inline images on HTML export.

AVIF is well supported by browsers these days and offers similar
features and much better compression than the other image formats
commonly used for the web.
