Remove vis and AggConfig docs

[timroes]

Summary

This PR removes the documentation on vis and aggConfig. Both are going to change drastically (or rather vanish completely) with the change towards using Canvas expressions for all visualizations (#19813). It has also shown in the past, that even though our JSDoc stays updated, this documentation often were not aligned properly with the code, why we decided to remove it for now. We hope to bring a similar documentation (on the new APIs) back in a more stable way, via properly compiling JSDoc.

Instead of removing it completely, don't you think we can leave it blank with a small description says that it is outdated, code is changing fast and it's better to check the jsdocs directly on the specific files? Just to avoid people questions about: here where is the vis documentation? why it was removed?

[timroes]

I would rather have people reading this PR and seeing it, because referring to the code will bring us the very same problem: A file is moved (or even just renamed from .js -> .ts) and suddenly those links are no longer valid.

i agree with marco, i wouldn't expect someone in 2 months wanting to develop something with kibana to go thru our git history, find this PR, ... lets make life easier for our users ? :)
