Qiskit release notes: the latest major version should be open by default

[Eric-Arellano]

In docs/api/qiskit/release-notes, @1ucian0 requested that the newest major version is open by default:

We can do that by simply adding open to the <details>, like this:

<details open>
<summary>v2</summary>
- [v2.2](./2.2)
- [v2.1](./2.1)
- [v2.0](./2.0)
</details>

You'll need to modify this function to take an additional argument like kwargs: {isLatestVersion: boolean}. Change how <details> is set up based on it.

Update the call site to set isLatestVersion if it's the first entry in the for loop. You could switch the for loop to instead be a call to .forEach((version, idx) => ...)
