Describe the fix.

When on the page https://docs.quantum-computing.ibm.com/api/qiskit and I try to click "qiskit" section under the API References (see screenshot), I am taken to the link https://docs.quantum-computing.ibm.com/api/qiskit/index and getting a 404.

The URL https://docs.quantum-computing.ibm.com/api/qiskit/index no longer breaks. Although it's still a little weird to refer to it with the /index since it should solely be /api/qiskit.

There's no longer a user bug, at least, though. So this can drop in priority.

The problem is here:

documentation/docs/api/qiskit/_toc.json

Lines 5 to 8 in 5768b65

	{
	"title": "qiskit",
	"url": "/api/qiskit/index"
	},

Note that it's only a problem for Qiskit, not Runtime and Provider.
