Remove condition tutorial from doc index

[brson]

This tutorial no longer exists.

Sounds like #12539, but maybe we could repurpose this issue as to write a new one?

Why would you want to write a new condition tutorial if there aren't conditions?

[pnkfelix]

The original condition guide actually covered four separate topics on handling errors/exceptions ("or other rare events"), not just conditions:

• Options
• Results
• Failure
• Conditions

I suspect that once Conditions were gone, @alexcrichton figured there was little point in keeping the guide, though I suspect there might be some value in documenting the distinction between handling errors via Result-chaining versus Failure.

The recent PR #13499 is relevant, someone suggested putting parts of it in an error handling tutorial.

We should settle on whether we want a tutorial to deal with this or if we want to defer to rustdoc docblocks.
The main advantage of adding back a guide being that we would have a centralized place to present all forms of error handling.

I would like an error handling guide.
