Improve accessibility of TOC links by adding "title" attr

I don't see how this improves accessibility. It only repeats information that is already there.

If you want to work on accessibility issues, look into the tickets in https://github.com/dokuwiki/dokuwiki/projects/5

There's some programs like NVDA (Non Visual Desktop Access) that uses title attr of links and images to parse text of links and images. In some templates, like "Read the Dokus", instead of showing the text hovered of on TOC, it shows the page title, as can be seen below when hovering the "Information" subtopic.

It doesn't seems to be HTML error on template itself because it calls the tpl_toc() function to render the TOC.

Not a good idea.

Please read https://www.a11yproject.com/posts/creating-valid-and-accessible-links/
Notably the section

It is therefore not recommended to use the title attribute on elements. If you do use it don't double up on the accessible name of the link, this can produce unnecessary duplicate announcements to some screen readers.

In that case, where title overrides the link text, it would also cause a trouble for screen readers which would not read the link as expected. There's seems to be no error on HTML side. I'll mark @my17560 on this issue so maybe he could provide useful info, as it may be a specific template issue.
Edit: It seems that the latest update for the template seems to fix this issue.
