In API script, increase the number of headings on the right

[beckykd]

URL to the relevant documentation

Example where we really need more headings: https://docs.quantum-computing.ibm.com/api/qiskit/compiler#compilation-routines

Same file in Qiskit.org: https://qiskit.org/documentation/apidoc/compiler.html#qiskit.compiler.transpile

Please describe the UI problem.

There's no way to find the areas that you need in the topic I linked above. Note that in the Qiskit version, the sections on the right have titles that aren't in the actual document, so I have no idea where they came from.

1 Docs screenshot and Qiskit screenshot are attached.
