Typo in TOC for Images

[mycaule]

• [x] Fix images link in Table of Contents.
• [x] The TOC is actually pretty outdated, Regenerate TOC
• [x] Delete one link, "SlidesJS is obsolete and no longer maintained", see nathansearles/slidesjs

Feel free to update it accordingly. Making just a noun plural adds not much value if you think there're bigger changes needed in the table of content.

Well the link didn't work before my change, so it is a simple but big improvement haha !

[gokaygurcan]

Let's wait for the infamous validator, and merge it then. Cheers!

[mycaule]

Thanks I actually deleted the broken link validator found and regenerated the TOC completely using this online tool. https://luciopaiva.com/markdown-toc/

The TOC now looks ok, there were plenty of links missing under Utils.

(up) this is ready

It's nice work, don't get me wrong, but why we removed "utilities" and "ui" sections?

[mycaule]

Because it is not here anymore, I regenerated the summary based on what is on the document right now.

[gokaygurcan]

I don't really think they ever existed. Both UI and Utilities were "logical groups" for some of the topics. I understand what "Notifications" mean there but also having a hard time to put it in a context. You see my point?

[mycaule]

Thanks, I have just indented UI and Utilities as groups as you recommended.

For the Utilities group it doesn't seem organized enough for me. It currently contains Files, Functional Programming, ... Machine Learning, ..., Benchmark.

It would also be clearer to use markdown section levels.

## Utilities
### Files
...
## UI
### Code highlighting
...

it's ready tell me what you think
