Communicate to users which requirements are necessary for the notebook

[Eric-Arellano]

This is quite similar to https://github.com/Qiskit/documentation/issues/922, but a bigger scope that we need to communicate what all the top-level requirements are for the notebook. For now, those are the same thing actually:

https://github.com/Qiskit/documentation/blob/124e14359dd1da55fa34ff2ffe2d0c06ab0155a0/scripts/nb-tester/requirements.txt#L3-L10

All the non Qiskit requirements are not directly imported. But there will be some tutorials in tutorials/ that may use additional tools like rustworkx. We need to signal to the user what they should install.

This would be nice to automate, although we have to keep in mind that the tutorials/ folder is deployed to a different app than docs/. That implies we can't easily use an MDX component like <VersionTable>. We'd need to insert the version information into the tutorials/ notebook folders at build-time, not run-time.

Ideally we could list which versions were used, but this isn't a hard requirement.
