Remove title from elements on Org mode (go-gitea#27968)

The Org mode rendering has some problems:
1.  `[[https://example.com][pre https://example.com/example.mp4 post]]`
 renders as
`<p><a href="https://example.com" title="pre <video
src="https://example.com/example.mp4"
title="https://example.com/example.mp4">https://example.com/example.mp4</video>
post">pre <video src="https://example.com/example.mp4"
title="https://example.com/example.mp4">https://example.com/example.mp4</video>
post</a></p>`
As you can see, the `title` attribute contains the inner html in
unescaped form. I removed the `title` attribute because it is of little
value.
3. The `title` attribute on `img` and `video` is of little value.
4. The inner elements of `video` are different depending on the `if`.
